Question

Where would electrons in the d sub level be found

Answer 1

d sub level starts from the 3rd energy level; means you can see electrons in d sub level in any energy levels after third one.

So the answer is "In any energy levels ≥ 3"

A simple information ; s sub level is in any energy level,

p sub level is in any energy level beginning from the 2nd energy level,

d sub level appears ≥ 3rd energy level

f sub level appears in 4th energy level and over.

Hope it helps!
