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.
