Molecular Formula. Molecular formula is the formula showing the type of atoms and number of each atom connected in the molecule. Therefore, it gives the correct stoichiometry of each atom. The atoms are depicted by their symbols, which are shown in the periodic table. And the numbers of atoms are written as subscripts.
â¢ Chemical formulas can often be written from the names of covalent and ionic compounds. â¢ A chemical equation uses chemical formulas, chemical symbols, and coefficients to describe a reaction. â¢ A balanced equation has the same numbers and kinds of atoms on each side of the equation.
