What are cations?

Back

Cations are positively charged ions formed when an atom loses electrons.

Front

What is the difference between ionic and covalent compounds?

Back

Ionic compounds are formed from the transfer of electrons between atoms, while covalent compounds are formed from the sharing of electrons.
