Is there solid oxygen, solid nitrogen, etc. etc.? If so what's it used for? If not is it because we don't have the technology or is it because the solid form is useless?

Hi does magnesium tetrachloride have a giant ionic structure or simple covalent structure?
It makes sense to be covalent, since it needs four covalent bonds to get a full outer shell - which it gets from the four chlorine atoms. But they're metal and non-metal, so they may somehow be ionic...

I'm doing a science experiment, and I need to see what agents I can use to show if calcium is present in a solution.

Help!

A) F
B) Br
C) Po
D) Pb

I picked C, because it has the largest atomic mass, and the polarizability is directly related to the atomic/molecular mass.

Yet somehow the answer is D.

The question is followed one.

Which has the smallest polarizability?
A) Si
B) S
C) Te
D) Bi

I picked Si, because it has the lowest atomic mass. Again, the answer is different. The correct answer is written as B.

What am I doing wrong?

Are the shells which the electrons occupy to be taken into account?
