A) What is an atomic orbital? What are the 4 different orbitals?

b) What do you notice about the sublevels as you
increase in energy level?

c)Are all orbitals found in each energy level?

See explanation

Explanation:

An atomic orbital is a region in space where there is a high probability of finding  an electron. The four different orbitals are s, p, d and f.

b) As you increase in energy level, the sublevels become farther from the nucleus and more diffuse. The energy associated with those sublevels increases likewise.

c) No, all orbitals are not found in each energy level because the maximum allowable value of l (orbital quantum number) in each energy level is n-1. Hence, n=1 only has the s orbital. n=2, has a maximum of the p orbital, n=3 level may accommodate the d orbital while n=4 and above may accommodate the f orbital. This is because, the orbitals s, p, d, f corresponds to orbital quantum numbers 0, 1, 2, 3.
