    Hi guys
    I am looking my notes of variable oxidation states of transition metals

    for general trends
    it says that
    relativity stability of +2 state with respect to +3 state increases across a period

    CAN SOME EXPLAIN WHY THIS HAPPEN?
    i looked online and what I understand is that across a period number of proton increases and atomic radius decreases so there is a more electrostatic attraction between the nucleus and outer electerons...is that right?/
