Question

nickel
express your answer in complete form, in order of increasing orbital. for example, 1s²2s² would be entered as 1s^22s^2.

Explanation:

Step1: Recall nickel's atomic number

Nickel has atomic number 28.

Step2: Write electron - configuration

Electrons fill orbitals in order of increasing energy. The electron - configuration of nickel is $1s^22s^22p^63s^23p^64s^23d^8$.

Answer:

1s^22s^22p^63s^23p^64s^23d^8
