Answer
a. 5s and 6s orbitals have the same shape and the maximum number of electrons.
b. 3p and 4p orbitals have the same shape and the maximum number of electrons.
c. 3s and 4s sublevels have the same shape and the maximum number of electrons.
d. 2s and 2p orbitals are in the same energy level.
Work Step by Step
a. the maximum number of electrons at the s orbital is 2, and they have a spherical shape.
b. the maximum number of electrons at the p orbital is 6, and they have two lobes.
c. the maximum number of electrons at the s orbital is 2, and they have a spherical shape.
d. orbitals 2s and 2p are both in level 2.
