2022: ☢️ Valence Electrons in Cobalt (Co) [& 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 Cobalt have?

In the case of Cobalt the valence electrons is 2,3. Now let's check the facts about Cobalt...

Atomic Symbol

Co

State at 20 °C

Solid

Description

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

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.

Name Origin

German: kobold (goblin).

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.

Discovery

Discovered By: George Brandt
Year: 1739
Location: Sweden

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:
