Answer:
Sulfur is a non mental, because it is consistent with the 3 physical properties listed for nonmetals
orbital velocity is a velocity that causes a natural or artificial satellite to remain in orbit
it can also be defined as the velocity at which a body revolves about another body
hope that helps !
Answer:

Explanation:
Hello.
In this case, given the volume (1cm³=1mL) and density of the bromine we are to firstly compute the mass since it will allow us to compute the representative particles:


Next, since the mass of one mole of diatomic bromine is 159.82 g (one bromine weights 78.91), we can next compute the moles in that sample:

Finally, via the Avogadro's number we can compute the representative particles of bromine as follows:
