Answer 1

Answer:

hey

Explanation:

Electron can be removed from 4s2

Zn+2= [Ar]4s1 3d^10

hope it helps..

Answer 2

Answer:

Explanation:

ATOMIC NUMBER OF Zn = 30

BELONGS TO D- BLOCK.

Zn = 1 s² 2 s² 2 p⁶ 3 s² 3 p⁶ 4 s² 3 d ¹⁰[ FILLING OF ORBITALS IN THIS ORDER]

BEFORE REMOVING ELECTRONS THIS SEQUENCE MUST BE REARRANGED IN INCREASING NUMBER OF QUANTUM NUMBER.

Zn = 1 s² 2 s² 2 p⁶ 3 s² 3 p⁶ 3 d¹⁰ 4 s².

NOW BY REMOVING TWO ELECTRONS:

Zn²⁺ = 1 s² 2 s² 2 p⁶ 3 s² 3 p⁶ 3 d¹⁰.

HOPES THIS HELPS.
