For nickel, Z=28Z=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:

NiNi, Z=28Z=28: 1s^(2)2s^(2)2p^(6)3s^(2)3p^(6)4s^(2)3d^(8)1s22s22p63s23p64s23d8

Are there 28 electrons?
