What is a Lewis structure?

Back

A diagram that shows the bonding between atoms of a molecule and the lone pairs of electrons that may exist.

Front

What does the octet rule state?

Back

Atoms tend to bond in such a way that they have eight electrons in their valence shell.

Front

What is a covalent bond?

Back

A chemical bond that involves the sharing of electron pairs between atoms.

Front

What is the difference between a single bond and a double bond?

Back

A single bond involves one pair of shared electrons, while a double bond involves two pairs of shared electrons.

Front

What are valence electrons?

Back

Electrons in the outermost shell of an atom that are involved in forming bonds.
