NEUTRONS:

ROUNDED ATOMIC MASS – ATOMIC NUMBER

FOR EXAMPLE…CARBON ATOMIC MASS = 12.011…ROUNDED IS 12 ATOMIC NUMBER = 6

12 – 6 = 6 NEUTRONS

VALENCE ELECTRONS:

• Electrons that are involved in transfer or sharing

• Located in the outer level of the atom

• Not all electrons in an atom are involved in the sharing or transferring

• 2 ways to represent the number of valence electrons:

• The Bohr Model

• Lewis Structure
