Sagot :
Answer:
2-8-16-2.
Explanation:
Located in the fourth period on the table of elements, nickel is a transition metal sandwiched between cobalt and copper. As each element adds an electron to one of the orbits, nickel adds its additional electron to the third orbital. It creates the electron configuration of 2-8-16-2.
Ni electronic configuration: [Ar], 3d8, 4s2
Atomic Number of Nickel (Ni) = 28
Electronic configuration is 1s2, 2s2, 2p6, 3s2, 3p6, 4s2, 3d8
or [Ar], 3d8, 4s2
where [Ar] is Argon with atomic number 18
