Answer:C
Explanation:
The orbital in question is the 3d orbital. The d-sublevel only contains a maximum of ten electrons in its five degenerate orbitals dxy,dyz,dxz,dz2 and dx2-y2. This is obtained the fact that each degenerate orbital holds only two electrons each.
Answer:
a covalent would be the two that are nonmetals
high energy to Low energy
=the electron gains energy (K.E)
