Question

Which of the following electron configurations is correct for nickel (atomic number 28)? *​

Answer 1

Answer:

Nickel atoms have 28 electrons and the shell structure is 2.8. 16.2. The ground state electron configuration of ground state gaseous neutral nickel is [Ar]. 3d8.

Answer 2

Answer:

The electronic  configuration of Nickel is 1s²2s²2p⁶ 3s² 3p⁶3d⁸ 4s²

Explanation:

The atomic number of Nickel is 28. These 28 electrons will get distributed in K,L,M and N shells,

Each Shell can accommodate certain number of electrons.

K can carry 2 electrons

L can carry 8 electrons

M can carry 18 electrons
