2022: ☢️ Electron Affinity of Calcium (Ca) [& Color, Uses, Discovery ...

In chemistry, the electron affinity of an atom of Calcium is defined as the amount of energy released or spent when an electron is added to a neutral atom in the gaseous state to form a negative ion. But what is the electron affinity of an atom of Ca?

In the case of Calcium the electron affinity is 2.37 kilojoules per mole.  There are a lot of cool facts about Calcium that most people don't know. Check this...

Calcium Facts

Calcium Electron Affinity

2.37 kilojoules per mole

State at 20 °C

Solid

Discovery

Discovered By: Sir Humphrey Davy
Year: 1808
Location: England

Uses

Used by many forms of life to make shells and bones. Virtually no use for the pure metal, however two of its compounds are, lime (CaO) and gypsum (CaSO4), are in great demand by a number of industries.

Sources

Obtained from minerals like chalk, limestone & marble. Pure metal is produced by replacing the calcium in lime (calcium carbonate, CaCO3) with aluminium in hot, low pressure retorts.

Description

Fairly hard, silvery-white metal. Fifth most abundant element in the earth's crust (41,500 ppm). Occurs only in compounds.

Atomic Symbol

Ca

Name Origin

Latin: calx, calcis (lime).

Citation

When you need to include a fact or piece of information in an assignment or essay you should also include where and how you found that piece of information.

That gives credibility to your paper and it is sometimes required in higher education.

To make your life (and citation) easier just copy & paste the information below into your assignment or essay:

Luz, Gelson. "Electron Affinity of Calcium (Ca) [& Color, Uses, Discovery ..." Materials. Gelsonluz.com. dd mmmm. yyyy. <URL>

Now replace dd, mmmm and yyyy with the day, month, and year you browsed this page. Also replace URL for the actual url of this page (The < and > stay, ok?). This citation format is based on MLA.
