Chlorine vs. Bromine

Chlorinenoun

A toxic, green, gaseous chemical element (symbol Cl) with an atomic number of 17.

Chlorinenoun

(countable) A single atom of this element.

Chlorinenoun

One of the elementary substances, commonly isolated as a greenish yellow gas, two and one half times as heavy as air, of an intensely disagreeable suffocating odor, and exceedingly poisonous. It is abundant in nature, the most important compound being common salt (Sodium chloride). It is powerful oxidizing, bleaching, and disinfecting agent. Symbol Cl. Atomic weight, 35.4.

Chlorinenoun

a common nonmetallic element belonging to the halogens; best known as a heavy yellow irritating toxic gas; used to purify water and as a bleaching agent and disinfectant; occurs naturally only as a salt (as in sea water)

Chlorine

Chlorine is a chemical element with the symbol Cl and atomic number 17. The second-lightest of the halogens, it appears between fluorine and bromine in the periodic table and its properties are mostly intermediate between them.

Brominenoun

(uncountable) A nonmetallic chemical element (symbol Br) with an atomic number of 35; one of the halogens, it is a fuming red-brown liquid at room temperature.

Brominenoun

(countable) A bromine atom in a molecule

Brominenoun

One of the halogen elements, related in its chemical qualities to chlorine and iodine. Atomic weight 79.8. Symbol Br. It is a deep reddish brown liquid of a very disagreeable odor, emitting a brownish vapor at the ordinary temperature. In combination it is found in minute quantities in sea water, and in many saline springs. It occurs also in the mineral bromyrite.

Brominenoun

a nonmetallic largely pentavalent heavy volatile corrosive dark brown liquid element belonging to the halogens; found in sea water

Bromine

Bromine is a chemical element with the symbol Br and atomic number 35. It is the third-lightest halogen, and is a fuming red-brown liquid at room temperature that evaporates readily to form a similarly coloured vapour.
