Q. Name a non-metal which is in liquid state at room temperature.
Ans:– Bromine is the only non-metal which exists in the liquid state at room temperature.
Non-metals
Non-metals are elements that absorb or gain electrons to generate negative ions. The outermost shell of non-metals normally has 4, 5, 6, or 7 electrons.
- Heat and electricity conductivity are weak in nonmetals.
- In all three stages, nonmetal elements exist.
- Nonmetals are brittle and can break down into smaller pieces due to their electronegative character.
- All nonmetals, with the exception of diamond, are soft in nature.
Bromine
Bromine (Br) is a halogen element and a member of Group 17 (Group VIIa) of the periodic table. It is a deep red toxic liquid and oily liquid with a sharp smell.
Bromine is employed in a variety of industries, including agriculture, dyes, pesticides, medicines, and chemical intermediates. Some usages are being phased out due to environmental concerns, while new ones are being discovered all the time.
- Flame retardants can be made from bromine compounds. They are used to make furniture foam, electronic plastic casings, and textiles less flammable. However, bromine has, however, been phased out as a flame retardant in the United States due to toxicity concerns.
- Halon fire extinguishers, which are used to put out flames in museums, planes, and tanks, contain organobromine. In film photography, silver bromide is a chemical.
- Before leaded fuel was phased out, bromine was used to make 1,2-di-bromoethane, an anti-knock compound.
