All atoms have a group name assigned, even Cobalt. Ok but how do we know what is the group name for an atom of Co?
If we know the symbol, let's say Co, we may then open any periodic table and search for Cobalt. Any decent periodic table should have the group numbers when you scroll up starting from the element you found.
In the case of Cobalt the group number is 9. There is a lot of cool stuff about Cobalt that people simply don't know. Why not stick around for a bit?

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. "Group Number Cobalt (Co) (& Color, Uses ..." 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.

Name Origin
German: kobold (goblin).Atomic Symbol
CoDescription
Hard, ductile, lustrous bluish-gray metal. Exists in the earth's curst in cocentrations of about 25 ppm. It has remarkable magnetic properties.State at 20 °C
SolidDiscovery
Discovered By: George BrandtYear: 1739
Location: Sweden
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.Want to learn more details and data about Cobalt (Co)? Check my Elements Comprehensive List.
