why does bromine being a liquid nonmetal, denser than all other nonmetals?
Answers
Smelly element No. 35, bromine, is a fairly abundant element but has a rare property: it is the only nonmetal to exist in liquid form at room temperature, and one of only two elements (the other being mercury) that is liquid at room temperature and pressure.
Answer:
Since liquid have more force of attraction between it's particles as compared to gas so bromine being a liquid non metal is denser than other non metal like as oxygen because it is in gaseous form.
It all depends on how much force of attraction is present between the particles of an element. These are exceptions chemistry has too many exceptions.
Like----Diamond is the strongest matter more than that of any metal and it's a non-metal's allotrope. It is just because of its tight bonding.
