What is the Lewis Dot Structure?

Back

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

What is a Bohr Model?

Back

A model of the atom that depicts electrons in fixed orbits around the nucleus, with each orbit corresponding to a specific energy level.

What are valence electrons?

Back

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

What is the significance of valence electrons in chemical bonding?

Back

Valence electrons determine how an atom can bond with other atoms.

Front

What is the atomic number of an element?

Back

The number of protons in the nucleus of an atom, which also equals the number of electrons in a neutral atom.

Front

What does the term 'octet rule' refer to?

Back

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