Question

A neutral atom in its ground state contains 28 electrons. this element is considered a ________ element, and has _______ electrons in orbitals with l = 2. actinide, 10 transition, 10 transition, 8 main group, 8 main group, 10

Answer 1

Answer:

transition, 8 electrons

Explanation:

The element in question is nickel. Nickel is a transition metal belonging to group10 in the periodic table. Its electron configuration is [Ar]4s2 3d8. Hence it has eight electrons in the d(l=2) orbital.

This is the ground state electron configuration of the transition metal nickel.

Answer 2

A neutral atom in its ground state contains 28 electrons. this element is considered a transition element, and has 8 electrons in orbitals with l = 2.
Electron configuration: ₂₈X 1s² 2s² 2p⁶ 3s² 3p⁶ 3d⁸ 4s².
l is azimuthal quantum number, l = 2 describes d orbital. There is eight electrons in 3d orbital.
