Question

How do you write the electron configuration for nickel?

Answer 1

For nickel, `Z=28`?

Explanation:

A nickel nucleus has 28 positively charged nuclear particles, 28 protons. The neutral nickel atom therefore must have 28 electrons to accommodate according to the usual scheme:

`Ni`, `Z=28`: `1s^(2)2s^(2)2p^(6)3s^(2)3p^(6)4s^(2)3d^(8)`

Are there 28 electrons?
