The atoms that would be expected to be diamagnetic in the ground state is magnesium
The magnetism of an atom refers to its electronic configuration. A diamagnetic atom is an atom whose electrons are all paired.
A paired electron is an electron that occurs in pairs in its orbital shell.
At their respective ground state, the electronic configuration of the given elements are as follows:
The electronic configuration of magnesium is 1s²2s²2p⁶3s². As such its a diamagnetic atom.
The electronic configuration of Potassium is 1s²2s²2p⁶3s²3p⁶4s¹. Hence, Potassium has one unpaired electron in its outermost shell.
The electronic configuration of Chlorine is 1s²2s²2p⁶3s²3p⁵. Hence, Chlorine has one unpaired electron in its outermost shell.
The electronic configuration of Cobalt is 1s²2s²2p⁶3s²3p⁶3d⁷4s². Hence, the unpaired electrons of Cobalt in its outermost shell are three.
Therefore, the atoms that are diamagnetic in the ground state is magnesium.

A qualitative observation describes the characteristics of a substance without quantifying them.
Just pay attention in school big bones, stop asking people because if they mislead you that will not be good for you're college education.
<span>The skull, vertebral column, and thoracic cage are the main part of the axial skeleton.
So, the answer is that the skull, vertebral column, and thoraic cage form the axial skeleton.
If you look at a diagram of the axial skeleton you will see the bones of the head (skull) , the spine (vertebral column), and the rib cage (toracic cage)
