Question

what is ions? give some examples ​

Answer 1

Answer:

an atom or a molecule that has gained or lost one or more of its parts (electrons) and so has a positive or negative electric charge..

Answer 2

heya buddy ! here is ur answer...

An ion is an atom or group of atoms where the number of electrons is not equal to the number of protons

example - when chlorine takes an electron from sodium, and sodium gives that electron to chlorine, they become ions and form NaCl. Sodum is a cation (lost an electron and became positive) and chlorine is an anion (gained an electron and becomes negative) in this situation.

hope it helps....^_^
