Wta happens whenan atom forms an ion?

Answer 1

When an atom becomes an ion, it is because the atom now no longer has a neutral charge. Nothing really happens besides this, unless it reacts to a different element.

Answer 2

When an atom forms an ion, it gains or loses electrons, resulting in a positive or negative charge. A positively charged ion is called a cation, and a negatively charged ion is called an anion. This change in the number of electrons affects the atom's chemical properties and reactivity.
