Particles and charges: "ProTons are PosiTive" — both have the letter T. Neutrons are Neutral (no charge). Electrons are negative (they're on the outside, "ex" means out, and they're negative).
Atomic notation: "Big number on top = Mass (more letters = top), Small number below = atomic (Z = proton count)." Think: Z is at the bottom of the alphabet, and the atomic number is at the bottom of the symbol.
Neutrons formula: N = A − Z. Think "Neutrons Are (A) Zapped (minus Z)."
