In chemical compounds, covalent bonds form when

• the electronegativity difference between two atoms is very large.
• electrons are completely transferred between two metals.
• pairs of electrons are shared between two non-metal atoms.

• two non-metal atoms are attracted to each other by opposite charges.

What is it called when atoms share two pairs of electrons?

• A double bond
• A single bond
• A triple bond
• A quadruple bond
