Determining the number of Protons, Electrons, and Neutrons

+

Protons and Electrons

+

If not electrically charged (will be discussed later), the proton and electron number will be the same as + the atom number.

+

Neutrons

+

Neutrons can be determined by using this following formula:
+ Atomic Mass - Atomic Number = Neutron Number +

Examples

+
+ +

+ Proton: 11
+ Electron: 11
+ Neutron: 23 - 11 = 12 +

+
+
+ +

+ Proton: 6
+ Electron: 6
+ Neutron: 12 - 6 = 6 +

+
+

Ions

+ Electron count will be added or subtracted by ion charge.
+ If the ion charge is positive (cation / kation), subtract the electron count.
+ If the ion charge is negative (anion), add the electron count. For example: +
+ +

+ Proton: 6
+ Electron: 6 + 4 = 10
+ Neutron: 12 - 6 = 6 +

+
+
+ +

+ Proton: 6
+ Electron: 6 - 2 = 4
+ Neutron: 24 - 12 = 12 +
