Understanding the Composition of Pyrite (Fool's Gold)
How many atoms are required to make pyrite?
A. One atom
B. Two atoms
C. Three atoms
D. Four atoms
Answer:
To make a single molecule of pyrite, which is a compound of FeS2, three atoms are needed: one iron atom and two sulfur atoms.
Pyrite, often known as Fool's Gold, is a yellow, metallic mineral composed of the chemical compound FeS2. This compound indicates that each molecule of pyrite is made up of one Fe (Iron) atom and two S (Sulphur) atoms. Therefore, a single molecule of pyrite requires three atoms in total - one iron atom and two sulfur atoms.
