What happens to the valence electrons in an ionic bond?

Back

In an ionic bond, valence electrons are transferred from one atom to another.

What is a polar covalent bond?

Back

A polar covalent bond is a type of covalent bond where the electrons are shared unequally between the two atoms, resulting in a slight charge.

What is a metallic bond?

Back

A metallic bond is a type of bond found in metals where electrons are shared among a lattice of metal atoms, allowing for conductivity.
