It can be both.
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
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
Yes, silver can form a positive ion with a charge of +1. When silver loses an electron, it becomes a silver ion (Ag+).
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".
Helium is a neutral atom that has several isotopes and can become an ion.
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.
The charge of the silver ion is +1.
The silver ion is Ag+ and has the oxidation state of +1.
