My question is: can A through C even be considered molecules? I mean they carry the same charge so the explanation to the question doesn't make any sense. I understand that between Br2 and I2 , I2 will be bigger due to periodic trends. I am just confused why they would say that A-C are even molecules...

You might be over thinking this one. This question implies all of them are molecules (however unlikely they are 🙁 ) hence this question is just asking if one knows the trend of increasing radius (implying size).

A molecule is two covalently bonded atoms...like every one of these. When they are the same, it's just a molecule. When they are different, it is a compound, which is just a specific class of molecules.

Iodine has the largest radius (I>Br>Cl>F), so the I-I would have a higher total radius thus larger size than Br-Br or if it was bonded to any of the other atoms. Hope it helps!

yeah i understand that... (that's why i got the question right lol)

I was just wondering why they call A-C molecules (because as I mentioned earlier and you stated just now they are not..)

hmm..i guess it is not something common to see two halogens bound together that's why I was wondering why they are molecules..Thanks for the explanation

Yea, I wouldn't overthink it. It is uncommon, but still perfectly plausible (each atom has a full octet, after all).

yeah gotcha

yea my bad about that just re-read your question lol
