WebAug 15, 2024 · A graph showing the first ionization energies of the Group 1 atoms is shown above. Notice that first ionization energy decreases down the group. Ionization energy is governed by three factors: the charge on the nucleus, the amount of screening by the inner electrons, the distance between the outer electrons and the nucleus. WebNext we'll calculate the first variation of F. And we can break this into components by starting with the first variation Fc. δ ( 1) Fc = kc 2∮(2H + c0)2δ ( 1) (dA) + kc 2∮4(2H + c0)2(δ ( 1) H)dA Where the first order variation of ψ gives us: δ ( 1) dA = − 2Hψg1 / …
