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 -
