What is an ionic bond?

Back

A bond formed when electrons are transferred from one atom to another, resulting in the formation of charged ions.

What is a covalent bond?

Back

A bond formed when two atoms share one or more pairs of electrons.

Front

What is the octet rule?

Back

The principle that atoms tend to bond in such a way that they have eight electrons in their valence shell, achieving a stable electron configuration.

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons and the attraction between oppositely charged ions, while covalent bonds involve the sharing of electrons between atoms.
