Chemical Bonding

The number of valence electrons can be determined by finding this about an element...

• it's GROUP number

• it's PERIOD number

• it's atomic MASS

• it's atomic RADIUS

Electronegativity is...

• the ability of an atom to attract/ accept electrons
• the ability of an atom to lose electrons
• the energy required to remove an electron from a specific atom
• how easy it is to make friends.
