i had the same question on my science homework!
a subscript Number of atoms of that element in the molecule.
Oxygen does not have an element symbol of O5. The element symbol for oxygen is simply O, representing its atomic number 8.
The subscript, the little number below and after the element, tells how many atoms are in a single molecule.
The number placed below an element symbol in a chemical formula is called a subscript because it indicates the number of atoms of that element in a molecule or compound. The subscript is written slightly below the element symbol to differentiate it from the coefficient, which applies to the whole molecule or compound.
It is the subscripted number immediately after the chemical element symbol in the molecular formula. If there is no number, then only one atom of that element is in itExample:H2O means two H's plus one O in water,NH3 = one N and three H atoms in ammonia
The subscript to the left of the element symbol (unless it doesn't have a subscript; then the number of of atoms in the element is 1)

The number of atoms of each element present in a molecule is indicated by the subscript to the right of the element symbol in the chemical formula. For example, in H2O, there are 2 hydrogen atoms and 1 oxygen atom.
The coefficient times the subscripts in a chemical formula show you the number of atoms of each element for each substance in the equation.
The number after a chemical symbol in a chemical formula represents the number of atoms of that element in a single molecule. This number is called a subscript, and it indicates the ratio of atoms in the compound.
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.
Atoms are differentiated by their number of protons. This is equal to the atomic number of the element. Additionally, in chemical formulas, each element is represented by a unique atomic symbol.
