DIFFERENT
CONFIGURATIONS
ELECTRON
CONFIGURATION:
REPRESENTS THE
NUMBER OF
ELECTRONS IN A
EACH SHELL.
EXAMPLE:
2-8-18-36
1ST SHELL = 2
2ND SHELL = 8
3RD SHELL = 18
4TH SHELL = 36

HOW CAN THE
PERIODIC TABLE
HELP US?
II.B ATOMIC NUMBER (Z) :
EQUALS THE NUMBER
OF PROTONS
II.B ATOMIC MASS (A) :
EQUALS THE # OF
PROTONS + THE # OF
NEUTRONS
HOW CAN THE
PERIODIC TABLE
HELP US?
IT ALLOWS US TO
CALCULATE THE
NUMBER OF
PROTONS,
NEUTRONS, AND
ELECTRONS!
SKIP TO II.C.2
II.B HOW TO CALCULATE THE NUMBER
OF PROTONS, NEUTRONS, AND
ELECTRONS IN A NEUTRAL ATOM?
WHAT DOES NEUTRAL MEAN?
NO CHARGE!
II.B HOW TO CALCULATE THE NUMBER OF
PROTONS, NEUTRONS, AND ELECTRONS IN A
NEUTRAL ATOM?
PROTONS = THE ATOMIC NUMBER
IF THE ATOM IS NEUTRAL…HOW MANY
ELECTRON SHOULD THERE BE?
SAME AS THE NUMBER OF PROTONS!
ELECTRONS = THE ATOMIC NUMBER
NEUTRONS = ATOMIC MASS – ATOMIC
NUMBER
