Part A

What is wrong with thenotation 1s22s22p63s23p63d104s24p2 forgermanium (atomic number 32)?

	The 4s subshell should appear beforethe 3d subshell.
	The 3p subshell should have morethan 6 electrons.
	The 3d subshell can holdonly 8 electrons.
	The 4d subshell should receive electronsbefore the 4p subshell.

A

Correct

Part B

Why should the 4s subshell be filled beforethe 3d?

Why should the subshell be filled beforethe ?

	The 4s subshell has greater spherical symmetrythan the 3d subshell.
	The 4s subshell is farther from the nucleus thanthe 3d subshell.
	The 4s subshell is at lower energy than the3d subshell.
	The 4s subshell holds fewer electrons than the3d subshell.

Part C

Write the electron configuration for the Na+ ion, which hasten electrons.

Enter 3s^3 for 3s3 , etc. Separate thesubshells by spaces.

Part D

Write the electron configuration for the Br- ion, which hasthirty-six electrons.

Enter 3s^3 for 3s3 (e.g., 1s^2 2s^2).
