2022: ☢️ Valence Electrons in Calcium (Ca) [& Facts, Color, Discovery ...

A valence electron is an outer shell electron and may participate in the formation of a chemical bond. Ok but how many valence electrons does an atom of Calcium have?

In the case of Calcium the valence electrons is 2. Now let's check the facts about Calcium...

Atomic Symbol

Ca

State at 20 °C

Solid

Description

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

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.

Name Origin

Latin: calx, calcis (lime).

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.

Discovery

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

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. "Valence Electrons in Calcium (Ca) [& Facts, Color, 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.
