Questions & Answers

i)Give the Correct full electronic configuration for the Mg2+ ion, ii) and state why it is easier to form the 2+ state for Mg than Ben

i)Magnesium and Beryllium are group II elements, and form ions with a charge of +2. The electronic configuration of Mg+2 ion is:

1s^2 2s^2 2p^6

ii)It is easier for magnesium to form a cation than beryllium as beryllium has really high electronegativity and ionization energy due to:

  1. Small Atomic radius

  2. Lesser shielding effect (only 1 intervalence shell)
