Explanation:
Detailed explanation-1: -Greek prefixes (see the Table provided at the bottom of this page) are used to indicate the number of atoms of each nonmetal element in the chemical formula for the compound. Exception: if the compound contains one atom of the element that is written first in the name, the prefix “mono-” is not used.
Detailed explanation-2: -Explanation: Greek prefixes are used for binary (two element) molecular compounds.
Detailed explanation-3: -Do NOT use prefixes to indicate how many of each element is present; this information is implied in the name of the compound.
