Atomic Number of Cobalt (+ facts: Uses, Color and more...) 2022

Every atom has an atomic number, even Cobalt. But what is an "Atomic Number"?

The atomic number of a chemical element is the number of protons found in the nucleus of the atom of that element.

Ok so I'll take you through some interesting facts and data about Cobalt (That most people don't know).

Cobalt Overview

Atomic Number

27

Learn more about the atomic number.

Atomic Symbol

Co (Cobalt)

Description

Hard, ductile, lustrous bluish-gray metal. Exists in the earth's curst in cocentrations of about 25 ppm. It has remarkable magnetic properties.

Solid

Sources

Occurs in compounds with arsenic, oxygen and sulfur as in cobaltine (CoAsS) and linneite (Co3S4). Pure cobalt is obtained as a byproduct of refining nickel, copper and iron.

Uses

Used in many hard alloys; for magnets, ceramics and special glasses. Remains hard up to 982°C. Radioactive cobalt-60 is used in cancer therapy.
