Atomic Symbol 21 (& 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 21?

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

Scandium Overview

Atomic Symbol

Sc (Scandium)

Description

Fairly soft, silvery-white metal. Eighth most abundant 'rare earth' found in the earth's crust (5.0 ppm).

Sources

Occurs mainly in the minerals thortveitile (~34% scandium) and wiikite. Also in some tin and tungsten ores. Pure scandium is obtained as a by-product of uranium refining.

State at 20 °C

Solid

Uses

Scandium metal is used in some aerospace applications. Scandum oxide (Sc2O3) is used in the manufacture of high-intensity electric lamps. Scandium iodide (ScI3) is used in lamps that produce light having a color closely matching natural sunlight.
