Elements 5AChemical 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

Arsenic1. 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
