Terms

• Sedimentary Cycle

• Multivalent

• Allotropic

• Phosphate

• Organophosphate

Term 1

Sedimentary Cycle

-Elements moving from land to water to sediment (solid fragments of material that come from the weathering of rock and are carried and deposited by natural methods)

-The Sedimentary Cycle is known as

the Phosphorus Cycle.

Term 2

Multivalent/Polyvalent

-Having a valence of 3 or higher.

-found in nature in several allotropic forms

Term 3

Allotropic

-The existence of two or more

crystalline or molecular structural forms

of an element.

-It is found in nature in

several allotropic forms

Term 4

Phosphate -The existence, especially in the solid

state, of two or more crystalline or molecular structural forms of an

element. -Phosphorus is commonly found in the

environment as phosphates

Term 5

Organophosphate

-the general name for esters of phosphoric acid.

Ecological Importance

• Concentrated phosphoric acids are used in fertilizers for agriculture and farm production.

• Plant growth and development requires phosphorus

• Phosphorus is essential for early root development and hastens plant maturity.

• Phosphorus, mainly in the form of the ions, is an essential and important nutrient of both animals and plants.

Location• Present throughout the

universe

• Part of the atmosphere and the sun

• In meteorites

• Molten material

• Usually found in combination with oxygen

Biological Importance

• Phosphorus is a mineral that makes up 1% of a person's total body weight.

• Plants and animals- phosphorus is found in complex organic compounds in the blood, muscles, and nerves (ex: adenosine triphosphate: ATP, calcium phosphate)

• The main function of phosphorus is in the formation of bones and teeth

• It is important in utilizing the body's carbohydrates and fats.

• Phosphorus compounds are essential in the diet; they are added to foods and animal feeds (ex: Organic phosphates, ferric phosphate, tricalcium phosphate, and dicalcium phosphate)

Phosphate in the atmosphere

• None are found in the gaseous state

• Usually in liquid form

• Dust particles

Phosphate in the lithosphere

• Phosphorus is found in sedimentary rocks and soil

• Main mineral found in phosphate containing rocks is called apatite

• Phosphorus found in insecticides, fireworks, detergents, fertilizers, and matches

Phosphorus in the Hydrosphere

• Used by all marine creatures

• Circulated through the food chain or deep in the ocean floor

• Some phosphate deposited in the shallows

Phosphorus in the Biosphere

• Phosphorus is present in almost every living organism in the biosphere

• Essential nutrient for animals and plants
