"The Atom"

What are  the Properties of Calcium? Definition of Calcium
What is the definition of Calcium? It is a silvery, moderately hard metallic element that constitutes approximately 3.5% of the earth's crust and is a basic component of most animals and plants. It occurs naturally in limestone, gypsum, and fluorite.

The Physical and Chemical Properties are the characteristics of a substance, like Calcium, which distinguishes it from any other substance. Most common substances exist as States of Matter as solids, liquids, gases and plasma. Refer to the article on Calcium for additional information and facts about this substance.

Calcium Properties - What are the Physical Properties of Calcium?
What are the Physical Properties of Calcium? The Physical properties of Calcium are the characteristics that can be observed without changing the substance into another substance. Physical properties are usually those that can be observed using our senses such as color, luster, freezing point, boiling point, melting point, density, hardness and odor. The Physical Properties of Calcium are as follows:

  • Color: Silvery-white metallic

  • Phase: Solid

  • Hardness: Relatively soft metal

  • Crystalline structure: Cubic

  • Ductility: It can be beaten into extremely thin sheets. It can be pressed, rolled, and cut

  • Malleability: Capable of being shaped or bent

  • Melting point: Melting point is 851C

  • Boiling point: Boiling point is 1482C

Calcium Properties - What are the Chemical Properties of Calcium?
What are the Chemical Properties of Calcium? They are the characteristics that determine how it will react with other substances or change from one substance to another. The better we know the nature of the substance the better we are able to understand it. Chemical properties are only observable during a chemical reaction. Reactions to substances may be brought about by changes brought about by burning, rusting, heating, exploding, tarnishing etc. The Chemical Properties of Calcium are as follows:

  • Chemical Formula: Ca

  • Oxidation: Used as a deoxidizer in steel

  • Isotopes: Six

  • Compounds: Compounds include limestone, marble, and gypsum

  • Flammability: When heated in air or in oxygen it ignites

  • Reactivity with water: Reacts with cold water rapidly at first, but the reaction is then slowed due to the formation of a film of Calcium hydroxide - Ca(OH)2

  • Reactivity with acids: Highly reactive
