Question

1. germanium (ge)

electron configuration:
noble gas configuration:

1. sulfur (s)

electron configuration:
noble gas configuration:

1. nickel (ni)

electron configuration:
noble gas configuration:

Explanation:

Step1: Recall electron - filling rules

Use the Aufbau principle, Pauli - exclusion principle, and Hund's rule to fill electrons.

Step2: Determine atomic numbers

Germanium (Ge) has an atomic number of 32, sulfur (S) has an atomic number of 16, and nickel (Ni) has an atomic number of 28.

Step3: Write electron configurations

For Germanium (Ge):

• Electron Configuration: $1s^{2}2s^{2}2p^{6}3s^{2}3p^{6}4s^{2}3d^{10}4p^{2}$
• Noble Gas Configuration: $[Ar]4s^{2}3d^{10}4p^{2}$

For Sulfur (S):

• Electron Configuration: $1s^{2}2s^{2}2p^{6}3s^{2}3p^{4}$
• Noble Gas Configuration: $[Ne]3s^{2}3p^{4}$

For Nickel (Ni):

• Electron Configuration: $1s^{2}2s^{2}2p^{6}3s^{2}3p^{6}4s^{2}3d^{8}$
• Noble Gas Configuration: $[Ar]4s^{2}3d^{8}$

Answer:
