Electrons/Level

3. Calculating Number of Protons and Electrons
Atomic Number Cu
Copper
63.546 +2
Atomic Number for a neutral atom =
# of Protons and Electrons

4. Calculating Number of Neutrons Cu
Copper
63.546 +2
Neutrons =
Mass Number –
Atomic Number
If Most Common Isotope - Round Atomic Mass to nearest whole number so 64 AMU

5. Calculating Mass Number Cu
Copper
63.546
Mass Number = Sum of the protons and neutrons +2

6. Element Name followed by hyphen and then Mass Number
Isotope Name Cu
Copper
63.546
Element Name followed by hyphen and then Mass Number
ex. Copper - 64 +2

7. X Isotope Notation m Cu p Copper 29 +1 +2 63.546 2-8-18-1
m = mass number: # of Protons + Neutrons Cu
Copper
63.546 X m p +2
X = symbol of element
p = Atomic Number: # of protons 64
Ex = Cu 29
