Argon vs. Bromine

Published:

Argonnoun

The chemical element (symbol Ar) with an atomic number of 18. The third most abundant gas in the Earth's atmosphere, it is a colourless, odourless, inert noble gas.

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.

Argonnoun

(countable) A single atom of this element.

Brominenoun

(countable) A bromine atom in a molecule

Argonnoun

A colorless, odorless gas occurring in the air (of which it constitutes 0.93 per cent by volume), in volcanic gases, etc.; - so named on account of its inertness by Rayleigh and Ramsay, who prepared and examined it in 1894-95. Symbol, A; at. wt., 39.9. Argon is condensible to a colorless liquid boiling at -186.1° C. and to a solid melting at -189.6° C. It has a characteristic spectrum. No compounds of it are known, but there is physical evidence that its molecule is monatomic. Weight of one liter at 0° C. and 760 mm., 1.7828 g.

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.

Argonnoun

a colorless and odorless inert gas; one of the six inert gases; comprises approximately 1% of the earth's atmosphere

Brominenoun

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

Argon

Argon is a chemical element with the symbol Ar and atomic number 18. It is in group 18 of the periodic table and is a noble gas.

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.
