Explanation:

Step1: Find Ge's atomic number

Germanium (Ge) has an atomic number of 32, so it has 32 electrons.

Step2: List occupied sublevels

Using the Aufbau principle, the electron configuration of Ge is $1s^22s^22p^63s^23p^64s^23d^{10}4p^2$. The sublevels here are s, p, d.

Step3: Fill orbital diagram (Hund's rule)

• 1s: 2 paired electrons ($\uparrow\downarrow$)
• 2s: 2 paired electrons ($\uparrow\downarrow$)
• 2p: 6 electrons (3 orbitals, each with $\uparrow\downarrow$)
• 3s: 2 paired electrons ($\uparrow\downarrow$)
• 3p: 6 electrons (3 orbitals, each with $\uparrow\downarrow$)
• 4s: 2 paired electrons ($\uparrow\downarrow$)
• 3d: 10 electrons (5 orbitals, each with $\uparrow\downarrow$)
• 4p: 2 unpaired electrons (2 orbitals, each with $\uparrow$)

Answer:

13)

• $\square$ p
• $\square$ d
• $\square$ s
• $\square$ f (unselected)

1. Orbital diagram filled as:

• 1s: $\boldsymbol{\uparrow\downarrow}$
• 2s: $\boldsymbol{\uparrow\downarrow}$
• 2p: $\boldsymbol{\uparrow\downarrow}$, $\boldsymbol{\uparrow\downarrow}$, $\boldsymbol{\uparrow\downarrow}$
• 3s: $\boldsymbol{\uparrow\downarrow}$
• 3p: $\boldsymbol{\uparrow\downarrow}$, $\boldsymbol{\uparrow\downarrow}$, $\boldsymbol{\uparrow\downarrow}$
• 4s: $\boldsymbol{\uparrow\downarrow}$
• 3d: $\boldsymbol{\uparrow\downarrow}$, $\boldsymbol{\uparrow\downarrow}$, $\boldsymbol{\uparrow\downarrow}$, $\boldsymbol{\uparrow\downarrow}$, $\boldsymbol{\uparrow\downarrow}$
• 4p: $\boldsymbol{\uparrow}$, $\boldsymbol{\uparrow}$, $\boldsymbol{\square}$ (empty)
