chemistry help a level

Hi wondering if anyone can help me with this -
Why is the melting point of Sodium higher than that of phosphorus or sulfur?

Thanks in advance,
Daniel
Think about the type of bonding in Na vs S8 (sulfur) and P4 (phosphorus). Hint about the latter 2 compounds is the number of atoms present.
Oh BTW my response is about the order overall but obviously still makes sense for Na over the other 2 when u start thinking about bonding

They tend to ask about overall order that's y I mentioned the fact that it's S8 vs P4 bc that may be handy. If u need any chem help drop me a msg, I'm studying it at uni الحمد لله

Honestly ain't that bad. I fumbled it tho coz I was doing really well الحمد لله but come exam time (2019) I made some booky (weird) mistakes. Basically I was like mentally not there. idk what happened. Like I was depressed. Exam on Eid and 1 mark off A* lol. They done me dirty. But there's a blessing in everything coz now I'm not at a uni I wouldn't like (certain colleges) الحمد لله. Lesson is don't stress coz whatever happens is gonna happen by the will of Allah. Hidden blessing.

1 mark off is peakkkk. well done tho,A is still mad. If I scrape thru w a B. Happy days

Yes IMI (intermolecular interactions). For Na it's metallic bonding so much stronger than IMI. In the case of S8 and P4 as they r symmetrical and cancel out so yes only London dispersion forces. However as S has 8 atoms vs 4 it's London forces are stronger and therefore 2nd highest out of the 3.

My year they made the exams harder. Past papers I smashed الحمد لله but we move. I didn't get A* bc of stupid mistakes and I think it's bc Allah protected me. I got closer to Allah coz I went uni closer to home الحمد لله
