Oxidation -

  1. Element gains oxygen
  2. Oxidation number increases
  3. Ag → Ag^+ + e^- [Electron wala thing is on the RHS]
    1. Element loses electrons

Reduction -

  1. Oxidation number decreases
  2. Element gains electron
  3. O2 + 4e^- → 2O^2- [BALANCE when dealing with gasses, increase both the sides AND ELECTRONS TOO]

OILRIG - Oxidation Is Loss, Reduction Is Gain

Adding 2 half equations -

  1. Make the number of electrons in both the half equations the same
  2. Cancel them out and then combine both the LHS’ and the RHS’

Relative atomic mass (RAM) is a measure of the average mass of an atom of an element, relative to 1/12 of the mass of a carbon-12 atom. RAM is calculated using the weighted average of the masses of the naturally occurring isotopes of an element. RAM is also known as atomic weight.
