What is the physical state of non-metal element bromine?
Gaseous state
Plasma state
Solid state
Liquid state
Liquid state
Bromine (Br2тАЛ) is a chemical element in the halogen group (Group 17) of the periodic table. It is one of the only two elements, and the only non-metal, that exists in a liquid state at standard room temperature and pressure (25┬░C).
Bromine (Br2тАЛ) is a chemical element in the halogen group (Group 17) of the periodic table. It is one of the only two elements, and the only non-metal, that exists in a liquid state at standard room temperature and pressure (25┬░C).
Think of it like water that looks like blood; while most non-metals like oxygen or nitrogen are gases and carbon or sulfur are solids, bromine occupies the unique 'middle ground' of being a volatile, heavy, deep-red liquid.
Remember 'Bromine is a liquid' by associating it with the 'Br' in 'Brine' (a liquid solution of salt), though chemically distinct.
Br2тАЛ тАФ Chemical formula of diatomic bromine liquid
Bromine has a relatively high atomic weight and significant London dispersion forces between its diatomic molecules (Br2тАЛ). At standard room temperature, these intermolecular forces are strong enough to keep the molecules in a liquid state, yet weak enough to allow for significant vaporization, giving it its characteristic reddish-brown color and pungent fumes.
Bromine is a halogen (Group 17 element).
It is a volatile, reddish-brown liquid at room temperature.
The only other element that is liquid at room temperature is the metal Mercury (Hg).
Used in flame retardants
Important in water purification and disinfectant chemistry
Highly corrosive and toxic to human skin and respiratory systems
Fire extinguishing agents
Pharmaceutical production
Atomic number: 35
Standard state: Liquid (l)
Option A is incorrect because bromine is not a gas. Option B is incorrect as it is not a plasma. Option C is incorrect as it is not a solid.
D is correct тАФ Bromine is the only non-metal element that exists in a liquid state at standard room temperature.
Always remember the exception: Mercury (Hg) is the only liquid metal, while Bromine (Br2тАЛ) is the only liquid non-metal at standard conditions.
