Element
The article I just read contained a lot of nomenclature that I do not understand.
The number of atoms of each element in a covalent compound is determined by the compound's molecular formula, which indicates the types and quantities of atoms present. For example, in water (H₂O), there are two hydrogen atoms and one oxygen atom. The subscripts in the formula denote the number of each type of atom, and if no subscript is present, it implies one atom of that element.
