Which prefix indicates the number of atoms in a covalent compound?

The prefix that indicates the number of atoms in a covalent compound is used to denote how many of each atom are present in a molecule. In covalent nomenclature, prefixes are utilized before the names of the elements to convey this information clearly.

Mono- signifies one atom, Di- indicates two atoms, and Tri- refers to three atoms. Each of these prefixes serves a specific function in the naming of covalent compounds, providing clarity in chemical formulas. Therefore, when examining the answer options, it’s evident that each prefix contributes to the systematic naming of a compound based on the count of atoms.

Since all the prefixes listed indicate specific quantities, and they are employed in combination when naming covalent compounds, they collectively represent a complete range of atomic counts. Therefore, the correct answer encompasses all of these prefixes, demonstrating their unified role in denoting the number of atoms in covalent compounds.
