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 -

How to Read / Order

-
    -
  1. Start from the top-most arrow
    2. -
  2. Follow the direction of the arrow. For example;
    3. -
      -
    1. 1s, 2s, 2p, 3s
      2. -
    -
  3. Exponent the electron with maximum number of sub-shell until the total of exponents is equals to - Atom Number.
    4. -
  4. If the total is more than Atom Number, subtract the the last electron's exponent to make the total - equals to the atom number.

Electron Count Rules

Shell KWrite 2 if electron ≥ 2
Write 1 if electron < 2 (only for Hydrogen)
Shell LWrite 8 if electron ≥ 8
Write leftover electrons if electron < 8
Shell MWrite 18 if electron ≥ 18
Write 8 if 8 ≥ electron < 18
Write leftover electrons if electron < 8
Shell NWrite 32 if electron ≥ 32
Write 18 if 18 ≥ electron < 32
Write 8 if 8 ≥ electron < 18
Write leftover electrons if electron < 8

How to Determine Electron Count

-
    -
  1. Follow the rules
    2. -
  2. If the electrons (aka atomic number) = 0, you're done.
