What is an ionic bond?

Back

An ionic bond is formed when one atom transfers electrons to another atom, resulting in the formation of charged ions.

Front

What is a covalent bond?

Back

A covalent bond is formed when two atoms share pairs of electrons.

What is the octet rule?

Back

The octet rule states that atoms tend to form bonds in such a way that they have eight electrons in their valence shell.

What is the difference between polar and nonpolar covalent bonds?

Back

Polar covalent bonds occur when electrons are shared unequally between atoms, while nonpolar covalent bonds occur when electrons are shared equally.

Front
