Elements 5A Chemical Properties Nitrogen-Nitrogen form compounds through biological activity. Phosphorus-Phosphorus also combines with metals to form compounds known as phosphides. Arsenic-Arsenic combines with oxygen more slowly at room temperatures. The thin coating of arsenic oxide that forms on the element prevents it from reacting further. Antimony-It does dissolve in some hot acids, however, and in aqua regia. Aqua regia is a mixture of hydrochloric and nitric acids. It often reacts with materials that do not react with either acid separately. Bismuth-Bismuth combines slowly with oxygen at room temperature. Bismuth also reacts with most acids.

Nitrogen 1.Nitrogen is odorless, tasteless, and colorless. 2.Nitrogen gas (N2) makes up 78.1% of the volume of the Earth's air. Symbol: N

Phosphorus 1.Highly reactive, poisonous, non-metallic element occurring naturally in phosphates. 2.It is used in safety matches, pyrotechnics. Symbol: P

Arsenic 1. Arsenic is a naturally occurring substance, It occurs in several forms, often in compounds with other chemical elements. 2.Arsenic and all of its compounds are poisonous but the toxicity varies. Symbol: As

Antimony 1.An amorphous metastable form of the element formed by cooling gaseous antimony rapidly. 2.It is more chemically reactive than the metallic form of the element. Symbol: Sb

Bismuth 1.Bismuth is not known to be toxic. 2.Bismuth is a crystalline, brittle, metal. Symbol: Bi
