Aneutral 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

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.

heat or electricity in the atmosphere- c.

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
