Explanation:

When two compounds are made from specifically only of two elements, that compound is known as binary. Binary compounds can be of two types

1. where two elements are different and only one atom of each element would participate in compound making. some of the examples are: - sodium chloride (one sodium and one chlorine).

2. Where more than one atom of each element participate such as nitrous oxide (two atoms of nitrogen and one of oxygen).
