Calcium Metal

Metals have been an inseparable component of major civilizations since centuries. Although metals were utilized since time unknown, researchers put considerable efforts in giving them appropriate names and defining their different properties and characteristics. This nomenclature process helped in arranging these metals in a well-organized fashion, known as the periodic table. In this periodic table, Calcium metal is also represented by the symbol Ca. This atomic symbol of Calcium is useful in indicating the position of metal Ca in the periodic table. If you are curious-headed or a science-geek, the common questions about metals are What is Calcium? What are its physical, chemical, mechanical, electrical and thermal properties? Find all the relevant facts about Ca metals in the following sections.

Periodic Table of Calcium

Periodic table of Calcium comments over its position in the periodic table, on the basis of parameters like group number, period row, atomic number and orbital block. The metals which have electrons falling in the same sub-shell are grouped under the same block corresponding to its respective orbital. Calcium metal belongs to Alkaline Earth Metals category of the periodic table. Metals down a group have same valency while metals across a period have the same number of shells. Its group number (column number) is 2, whereas its period number is 4. It is placed under s block of the periodic table & is one of the prominent s block elements.

Calcium Metal Properties

Metals have certain properties by which they can be distinguished from one another. Magnetic and Atomic Structure of Calcium are few widely searched properties. Using the comparison facility, you can not only view the individual metal properties, but also compare the properties of multiple metals to get a thorough comparative analysis between the metals of your choice. Atomic number is a basic building block for the arrangement of metals in the periodic table. Atomic number of Calcium is 20 and its atomic weight is 40.08 amu. The electrons in its atom are arranged in orbitals as [Ar] 4s2. Nuclear particles in Calcium atom are 20 neutrons, 20 protons and 20 electrons.

Physical and Chemical Characteristics of Calcium

Physical and chemical characteristics of Calcium are two major criteria while comparing this metal with other metals. Physical Properties of Calcium include its external appearance, shininess at surface, color, etc. Properties like density, viscosity, melting and boiling point are also covered in this section. At room temperature, this metal is a Gray Solid. It starts melting at 839.00 °C. All these Calcium metal properties together define what is Calcium?
