Atomic Symbol 20 (& Cool facts: Uses, Sources, Color and more...) 2022

Every atom has a symbol and some are easy to figure out. Especially if you already know its name.

But what do you do when you only know its atomic number? Like... what is the atom symbol whose atomic number is 20?

The answer is Calcium (Ca). However there are a lot of interesting facts about Calcium that people don't know. Let me show you:

Calcium Overview

Atomic Symbol

Ca (Calcium)

Description

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

State at 20 °C

Solid

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.
