If we drew the atom to scale and made protons and neutrons a centimeter in diameter, then the electrons and quarks would be less than the diameter of a hair and the entire atom's diameter would be greater than the length of thirty football fields! 99.999999999999% of an atom's volume is just empty space!
Question: An Atom Has More Electrons Than Protons. The Atom Is An Insulator. A Negative Ion. A Conductor. A Positive Ion. A Semiconductor.
Encyclopædia Britannica, Inc. An atom that has more or fewer electrons in orbit than protons in its nucleus is called an ion. Once the electron from its valence shell has been transferred, the sodium atom will be missing an electron; it therefore will have a positive charge and become a sodium ion.
B. There are more protons than electrons. Explanation: When the number of protons is greater than that of the electrons, such an atom becomes positively charged. An atom is made up of three main subatomic particles which are the protons, neutrons and electrons. The electrons are negatively charged particles that moves round a central nucleus in ...
We will use the term shell rather than energy level but either is acceptable. The maximum number of electrons in each shell, going from the middle to the outside, is 2, 8, 8, 18. Below is a picture of a potassium atom. Its electron structure is 2, 8, 8, 1. An atom that has the maximum number of electrons in its outer shell will be stable.
Aug 06, 2020 · Since the vast majority of an atom’s mass is made up of its protons and neutrons, subtracting the number of protons (i.e. the atomic number) from the atomic mass will give you the calculated number of neutrons in the atom. The numbers after the decimal point represent the usually very small mass of the electrons in the atom.
An atom of carbon-14 has a greater mass than an atom of carbon-12. Likewise, an atom of uranium-235 is much more massive than an atom of carbon-14. It is important to note, however, that an atom’s mass number is not exactly the same as its mass.
The fact that protons and neutrons are very similar was understood almost immediately. But the fact that protons and neutrons have a measurable size, comparable in size to a nucleus (about 100,000 times smaller in radius than a typical atom), wasn’t learned til 1954. The atom with the extra electron now has a negative charge (because there are more electrons than protons) and is called a negative ion. And since opposites attract, the ions get it together to form molecules.
Jun 22, 2009 · A negative ION has more electrons than protons, a positive ION has less electrons that protons. Take the element, find its atomic number; that is the amount of protons. Take the mass (if it is...
This was more accurate than the Rutherford model. However, it was still not completely right. Improvements to the Bohr model have been made since it was first introduced. In 1925, chemist Frederick Soddy found that some elements in the periodic table had more than one kind of atom. For example, any atom with 2 protons should be a helium atom.
Apr 20, 2020 · We can use tools like the periodic table of elements to figure out exactly how many protons, and thus electrons, an atom has. First of all, we know that for an atom to have a neutral charge, it must have the same number of protons and electrons. If an atom loses or gains electrons, it becomes ionized, or charged.

Thus, an atom with one proton in its nucleus normally will have one electron in orbit (and be labeled a hydrogen atom); an atom with ninety-four protons in its nucleus will normally have ninety-four electrons orbiting it (and be labeled a plutonium atom). The number of protons in a nucleus is called the atomic number and always equals the number of electrons in orbit about that nucleus (in a nonionized atom). Thus, all atoms that have the same number of protons--the atomic number--are atoms ... Every atom of an element has the same number of electrons and protons. A neutral atom has equal numbers of electrons and protons. The atomic number Z gives the number of protons in the nucleus of an atom. In a neutral atom this is also equal to the number of electrons.
Similarly, every chlorine atom (atomic number = 17) has 17 protons; every uranium atom (atomic number = 92) has 92 protons. Isotopes. The number of neutrons in an atom can vary within small limits. For example, there are three kinds of carbon atom 12 C, 13 C and 14 C. They all have the same number of protons, but the number of neutrons varies.
Nitrogen has an atomic number of 7; the neutral Nitrogen atom has 7 protons and 7 electrons. If Nitrogen gained three electrons it would have 10 electrons, like the Noble gas Neon (10 protons, 10 electrons). However, unlike Neon, the resulting Nitrogen ionwould have a net charge of N3-(7 protons, 10 electrons).
I am unsure as to what your asking so I’ll provide two answers. A positive atom, one that has lost electrons, is called a Cation. They could also be referred to as valencies, for example Sodium can be a cation, that has lost an electron, and now h...
An argon in the ground state tends not to bond with an atom of a different element because the argon atom has? the choices are: 1. more protons than neutrons 2. more neutrons than protons 3. a total of two valence electrons 4. a total of 8 valence electrons
Apr 13, 2020 · Protons and neutrons have approximately the same mass, but they are both much more massive than electrons (approximately 2,000 times as massive as an electron). The positive charge on a proton is equal in magnitude to the negative charge on an electron. As a result, a neutral atom must have an equal number of protons and electrons.
Dr. Jones says an atom has 3 electrons in the first shell and four electrons in the second shell. Someone should tell Dr. Jones that ... a. No shell can hold more than 2 electrons. b. The first shell must fill before the second shell can have electrons. c. The first shell shouldn't have 3 electrons. d. The second shell should have 8 electrons. e.
so, as your question is about what will an atom be called when it has more protons than electron. is the protons are more in numbers, then, it is sure that there will be excess of positive charge. so that atom will be positively charged. and the positively charged atom that has lack of some electrons is called as cation or positive ion.
An 18O atom contains the same number of protons, neutrons, and electrons. 17) Using grammatically correct English sentences, describe what the isotopes of elements have in common. 2)
Jun 02, 2019 · A neutral atom has the same number of protons and electrons (charges cancel each other out). An ion has an unequal number of protons and electrons. If the charge is positive, there are more protons than electrons. If the charge is negative, electrons are in excess. You can find the number of neutrons if you know the isotope of the atom.
– It has one less electron than the number of protons. How many protons and electrons does a sodium ion, Na+, have? 35 Ions Ions differ from atoms in that they have a charge; the number of electrons is either greater than, or less than, the number of protons. Cations are positively charged. They have fewer electrons than in the neutral atom.
A neutral atom has the same number of protons and electrons (charges cancel each other out). An ion has an unequal number of protons and electrons. If the charge is positive, there are more protons than electrons. If the charge is negative, electrons are in excess.
\$\begingroup\$ Protons have that much more mass, not volume. The two are very different properties - in fact, for small particles like protons and electrons, bigger mass means occupying less space (or more accurately, less uncertainty in their position - neither electrons nor protons are little balls). \$\endgroup\$ - Luaan Oct 8 at 17:49

The numbers after the decimal point represent the usually very small mass of the electrons in the atom.
generally the electronic structure of an ion is very similar to that of the atom with the same number of protons as electrons because it is the electronic behaviour that dominates. This can be seen in the spectra of ionised atoms.
More recently we have come to understand the nuclear force using a theory called quantum chromodynamics (QCD), which describes protons and neutrons as being made up of quarks. In particular, the proton is thought of as a combination of two up quarks (uu) and a down quark (d), whereas the neutron is thought to consist of one up quark (u) and two ...
Dec 17, 2020 · Atoms have a certain number of electrons orbiting the nucleus. If the number of electrons is equal to the number of protons, the overall electric charge of the atom is neutral. If the atom has more electrons than protons, its charge will be negative. With fewer electrons than protons, the atom will have a positive charge.
Correct answer to the question: What does the nucleus of the atom contain? A. protons and electrons B. protons and neutrons C. neutrons and electrons
Sometimes atoms gain or lose electrons. The atom then loses or gains a "negative" charge. These atoms are then called ions. Positive Ion - Occurs when an atom loses an electron (negative charge) it has more protons than electrons. Negative Ion - Occurs when an atom gains an electron (negative charge) it will have more electrons than protons.
Isobars differ in atomic number (or number of protons) but have the same mass number. Here both M and N have equal number of proton and neutron but M contains more electrons than N thus N must be the cation of M.
Thus the carbon atom in the pencil’s lead has six electrons to match the protons. The third kind of subatomic particles, electrons, are the smallest in size and add virtually nothing to the mass of the atom. Each proton and neutron contained in the nucleus is about 1,837 times more massive than an electron.
Each atom has a neutral charge, and since a proton has a positive charge and an electron has a negative charge, in order to achieve a neutral charge, the number of protons and electrons must equal. A particle that is not neutral (has either more or less electrons) is known as an ion.
Normally, the number of electrons in an atom equals the number of protons and the overall charge of the atom is zero. However, atoms may gain or lose electrons: ¾If an atom gains electrons, it will have an extra negative charge for each electron gained. ¾If an atom loses electrons, it will have an extra positive charge for each electron lost. 14
