A binary compound is composed of exactly how many elements?

Explanation:
Binary compounds are defined by containing two different elements. The term “binary” signals two distinct elements to combine, not the total number of atoms in a molecule. For example, water is made from hydrogen and oxygen, so it’s a binary compound even though a single water molecule has three atoms in total. If a substance had three different elements, it would be a ternary compound, and if it were just one element, it wouldn’t be a compound at all. So, a binary compound is composed of two elements.
