Are atoms always neutral?
Question Date: 2019-11-03
Answer 1:

Yes, an atom is always neutral. This is because they have an equal number of electrons and protons. However, it is possible to remove or add electrons to an atom. This is usually done by some kind of chemical reaction. This turns the atom into what is called an ion. Ions have a net positive or negative charge since they no longer have an equal number of electrons and protons.
