The subscript number after the element symbol, such as the 2 in H2O, tells how many atoms in each molecule. In the example, the 2 refers to H (hydrogen). If there is no number present, then 1 is implied. So H2O has 2 hydrogen and 1 oxygen.
Barium is an element, with a chemical symbol of Ba. As an element it does not have a formula.
The chemical formula of the element Neodymium is Nd.
Any chemical element; it is an error.
The chemical formula for calcium chloride is CaCl2. A formula is determined by chemical analysis.
determined using the chemical formula of the compound. The chemical formula provides the type and ratio of elements present in a compound. After determining the chemical formula, one can calculate the exact number of atoms of each element in a unit of the compound using stoichiometry.
