What is a covalent bond?

Back

A covalent bond is a type of chemical bond where two atoms share one or more pairs of electrons.

Front

What is an ionic bond?

Back

An ionic bond is a type of chemical bond formed through the transfer of electrons from one atom to another, resulting in the formation of charged ions.

Front

What is a metallic bond?

Back

A metallic bond is a type of chemical bond that occurs between metal atoms, where electrons are delocalized and can move freely throughout the metal.

Front

What are hydrogen bonds?

Back

Hydrogen bonds are weak attractions that occur between a hydrogen atom covalently bonded to a highly electronegative atom and another electronegative atom.
