Water freezing point 0° c or boiling point 100° c.

Bromine is a non metal, which is at room temperature in liquid state.

This is a non-metal, it is reddish brown.

To exist a molecule together (group of atoms) there is some forces are working that force may be strong electrostatic force or force due to electron transformation or week van der waal forces.

Bromine is a brown coloured liquid.

Phosphorous is solid at room temperature.

Chlorine can either be gas or solid (chlorine tablets used for purifying water) and helium has gaseous nature in room temperature.

Bromine only is found in liquid form at room temp having brownish color.

Can anyone tell me how bromine in used in mobile phones?

At ambient temperature bromine is a brownish-red liquid. It has a similarly colored vapor with an offensive and suffocating odor. It is the only nonmetallic element that is liquid under ordinary conditions, it evaporates easily at standard temperature and pressures in a red vapor that has a strong disagreeable odor resembling that of chlorine. Bromine is less active chemically than chlorine and fluorine but is more active than iodine; its compounds are similar to those of the other halogens. Bromine is soluble in organic solvents and in water.

Can anyone tell me. What is the vander wall?

Bromine was discovered independently by two chemists, Carl Jacob Lowig and Antoine Balard, in 1825 and 1826.
