The term for a compound made from only two elements is called a binary compound.
Binary compounds are simple in nature, consisting of just two different types of elements. These compounds can be formed from a combination of metals and non-metals, or non-metals with other non-metals. For example, sodium chloride (NaCl) is a binary compound formed from sodium (Na) and chlorine (Cl). The naming of binary compounds typically follows specific rules in chemistry, often involving the use of prefixes to indicate the number of atoms of each element in the compound. Understanding binary compounds is fundamental in chemistry, as they serve as the building blocks for more complex substances.
