## Q. 4.6

Indicate the type and number of orbitals in each of the following energy levels or sublevels:
a.  $3p \space sublevel$             b.  $n = 2$           c.  $n = 3$           d.  $4d \space sublevel$

## Verified Solution

a.  The $3p$ sublevel contains three $3p$ orbitals.
b.  The $n = 2$ energy level consists of one $2s$ and three $2p$ orbitals.
c.  The $n = 3$ energy level consists of one $3s$, three $3p$, and five $3d$ orbitals.
d.  The $4d$ sublevel contains five $4d$ orbitals.
