Answer:

Step-by-step explanation:

electronic configuration for the Ni2+ is

1s2 2s2 2p6 3s2 3p6 3d6 in the ground state

more correctly the electrons are leaving the 4s2

nickel ni28 has 28 electrons 18 electrons fill up the third electron shell leaving 10 valance electrons.2 electrons in the 4s and 8 electrons in the 3d

when nickel Becomes ni+2 Nickel has lost 2 electrons leaving the atom with only 8 valance electrons

the 4s electrons at a lower energy level than the 3d electrons path of the s orbital. so in the ground state, the electrons being lost should be the 3d electrons leaving only the third shell electrons making the atoms more stable than losing the 3d electrons

the electronic configuration is that

1s2 2s2 2p6 3s2 3p6 3d8
