In one atom of cobalt ion, the number of neutrons can vary based on the isotope. The most common isotope of cobalt is cobalt-59, which has 33 neutrons.
A chromium ion is not neutral. By definition an ion is not neutral. All atoms belong to an isotope, but that has nothing to do with whether the atom is ionized or not.
it is batman
It can be both.
Yes, an isotope can also be an ion. An isotope is a variant of an element with the same number of protons but a different number of neutrons, while an ion is an atom or molecule with a net electric charge due to the loss or gain of electrons.
ion
An alumimium atom is electrically neutral and it is an isotope of aluminum.
they all have the same element with the same number
You call it an ion of that isotope. Let's use carbon-14 for example. If a carbon-14 atom gains/loses an electron, you simply call it a "carbon-14 ion".
This atom of Nitrogen with 7 protons, 7 neutrons, and 8 electrons is an isotope, specifically nitrogen-14. It is not an ion because it has an equal number of protons and electrons, so its charge is neutral. It is also not an average atom, as it has a specific number of protons and neutrons that define it as a particular isotope.
The ion charge is typically written as a superscript to the right of the element symbol in an isotope symbol. For example, if an atom loses one electron to become positively charged, the ion charge would be indicated as a +1 next to the element symbol.
Helium is a neutral atom that has several isotopes and can become an ion.
