It would depend on the isotope.
Protons and Neutrons.
The lithium ion is essentially the same as the lithium atom, except it has lost 1 electrons. The number of protons and neutrons remain the same. Thus, the lithium ion, Li+ has 3 neutrons, just like the lithium atom.

29, it's the same as the atomic number, unless it's an isotope or an ion
If the number of protons and neutrons are the same, its an atom, if not its an ion
Protons and Neutrons.
This is not an atom. This is an ion. This is Na+ ion.
The lithium ion is essentially the same as the lithium atom, except it has lost 1 electrons. The number of protons and neutrons remain the same. Thus, the lithium ion, Li+ has 3 neutrons, just like the lithium atom.

N-14 is the most common isotope of nitrogen atom and it has 7 protons, 7 neutrons
It would be an ion.
The neutral atom of cobalt has 27 electrons. The number can vary up or down depending on the chemistry of the sample of cobalt. A link is provided to the Wikipedia article on the element cobalt.
29. Cu 1 is an ion where the Cu atom has lost an electron. Therefore, it would have the normal 29 neutrons.
+ or - 4

8. When an atom becomes an ion, it gains or loses electrons. The number of protons and neutrons doesn't change. If the number of neutrons changes then the atom has changed into a different isotope.
