The Math of the Atom
How to read the architect's legend
1 Atomic Number
The "ID Card" of the atom.
Atomic # = Number of Protons
2 Atomic Mass
The weight of the nucleus.
Mass = Protons + Neutrons
EXAMPLE: HELIUM
2
He
4.0026
Protons = 2
Electrons = 2
Neutrons = 4 - 2 = 2
Solving for Neutrons
The most common mistake! Let's master it.
Step 1
Find Atomic Mass
(Round to nearest whole number)
Step 2
Subtract Atomic #
(This is your # of Protons)
Result
Number of Neutrons
Mass - Protons = Neutrons
