What does 'Fe' stand for?

Gold Iron Silver Copper

Correct Answer:

Iron

Explanation:

Fe is the chemical symbol for iron. Element symbols are short abbreviations for element names, and Fe comes from the Latin word Ferrum, which is why iron is written as Fe in chemistry and welding contexts. When you see Fe, think iron—the main component in steel and many structural metals. For contrast, gold is symbolized as Au, silver as Ag, and copper as Cu, so those symbols differ from Fe.
