Answer 1

The electronic configuration for Radium at ground state would be this one: but first, the ground state electron configuration is the organization of electrons all over the nucleus of an atom with lesser energy levels.

 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 4d10 5s2 5p64f14 5d10 6s2 6p6 7s²  or in other terms [Rn] 7s2 and the term symbol is 1S0.
