Chem 4.3 Part 3 Atomic Orbitals

What is the shape of an s orbital?

• Dumbbell-shaped

• Spherical

• Cloverleaf-shaped

• Donut-shaped

How many p orbitals are present in each shell, except the first one?

• 1

• 2

• 3

• 4

Which of the following correctly lists the orbitals in order of increasing energy within a shell?

• p < s < d < f

• s < p < d < f

• d < s < p < f

• f < d < p < s

Describe the shape of a d orbital.

• Spherical

• Dumbbell-shaped

• Cloverleaf-shaped

• Donut-shaped

Explain why the s orbital is spherical in shape.

• Because it has the highest energy

• Because the probability of finding an electron is the same in all directions

• Because it contains more electrons than other orbitals

• Because it overlaps with other orbitals

Which subshell will electrons fill first in a magnesium atom?

• 2p

• 3s

• 1s

• 2s

How do the energies of the 2p orbitals compare to the 3s orbital?

• 2p orbitals have more energy than the 3s orbital

• 2p orbitals have less energy than the 3s orbital

• 2p orbitals have the same energy as the 3s orbital

• 2p orbitals have no energy compared to the 3s orbital

Identify the correct order of subshells from lowest to highest energy for the following: 3p, 4s, 3d, 4p.

• 3p < 4s < 3d < 4p

• 4s < 3p < 3d < 4p

• 3p < 3d < 4s < 4p

• 3p < 4s < 4p < 3d
