The atomic number refers to the number of protons within an atom's nucleus and defines which element the atom is. And an ion is an atom with some level of positive or negative charge as a result of losing or gaining electrons, so ionisation has no effect on the atomic number (an ion of copper is still copper) and a negligable effect on the Atomic Mass - since electrons are relatively very light.
The only way the atomic number can change is through nuclear fission (elements decaying into isotopes and lower elements) or nuclear fusion (creating higher elements).
As such this question makes no sense.

Every element has its own atomic number the atomic number is the number of what?
the atomic number represents the number of protons in an elements atoms
What does the atomic number tells you?
The atomic number tells you how many protons and electrons are in a specific element.Atomic number tells us about protons. Number of protons that atom contains.
What determines the atomic number of a substance?
The atomic number is the number of protons in the nucleus of an atom, while the atomic mass is the total mass of the nucleus (both protons and neutrons)
Are most atoms neutral?
The atomic nucleus is not neutral, it is positively charged (the exact charge depends upon the element in question; the hydrogen nucleus is +1, the helium nucleus is +2, etc). The atom as a whole is electrically neutral, unless it becomes ionized.
What is a collection of atoms called?
A large collection of neutral atoms with the same atomic number is a sample of an element. Elements include include lithium, hydrogen, neon, and oxygen. Note that different isotopes of elements exist; these are atoms with the same atomic number but having a different number of neutrons.
How many electrons does Li-7 have?
3: The total number of electrons in any neutral atom is always the same as the atomic number of the element.
How is an atom's atomic number related to it's number of electrons?
For neutral atoms the atomic number is equal to the number of electrons.
In electrically neutral atoms the number of protons is the same as the number of .?
atomic number = number of protons = number of electrons (in a neutral atom)
How many neutral atoms does atomic number 117 and atomic mass of 294 have?
1. Every atom has a unique atomic number.
What does the atomic number of an element say about the number of particles in atoms of that element?
The atomic number is equal to the number of protons and neutrons in a neutral atom.
Can the neutral atoms of tow different element have the same number of electron explain?
NO. The number of electrons in any neutral atom must be the same as the number of protons. The number of protons is the atomic number, if the atomic number is the same then the atoms are of the same element, not different ones.
How many atoms does electrons have?
Atoms have 1 to 118 electrons. For a neutral atom the number of electrons is equal to the number of protons (atomic number).
What does the atomic number determmine?
Atomic number is the number of protons in the nuclei of the atoms of an element. It is the number of protons that determines the atomic number. In a neutral atom, the number of electrons equals the number of protons. So in a way you could say that atomic number determines the number of electrons in a neutral atom.
What are protons and electrons equal to on the periodic table?
The equivalence is with the atomic number.
What two things can you learn from the atomic number of an element?
The atomic number of an element is the number of protons in the nuclei of its atoms. If the atom is neutral, it is also the number of electrons.
How does the number of separate electrons shown for the group 2 metal atoms compare to the number of atoms?
The number of electrons in a neutral atom is equal to the atomic number.
What element has only three more electrons than germanium?
The element that has three more electrons than a neutral germanium atom is bromine. You can determine this by the atomic number. The atomic number of an element is the number of protons in the nuclei of its atoms. In a neutral atom, this is also the number of electrons. So, the atomic number of germanium is 32, so its neutral atoms contain 32 protons and 32 electrons. Move to the right three more elements, and you get bromine with an atomic number of 35, so its neutral atoms contain 35 protons and electrons.
