The subscript for H₂ is 2, indicating that there are two hydrogen atoms present in the molecule.
subscripts are the cation superscripts are the anian
subscripts
These subscripts are down the chemical symbol and at right. Example: O2
H2+ has a stronger bond than H2. The addition of a positive charge to the H2 molecule increases the attraction between the two hydrogen atoms, resulting in a stronger bond.
Chemical formulas are made of symbols representing elements and subscripts indicating the number of atoms of each element in a molecule.
Be + 2 HCl -> BeCl2 + H2, in which the second and third instances of the number 2 should be subscripts when that font is available.

Balancing only allows you to change the coefficients, NOT the subscripts.
These subscripts are down the chemical symbol and at right. Example: O2
Do you mean subscripts like H2O (ie the 2 would be subscripted)?
No, when the subscripts are changed, they become different compounds than the intended compounds.
You cannot.
No subscripts are needed: The formula unit for calcium oxide contains one calcium cation with a charge of +2 and one oxide anion with a charge of -2.
Changing subscripts in a chemical formula changes the actual chemical species present, leading to a different reaction. Subscripts represent the ratio of elements in a compound and should not be changed to balance chemical equations. Balancing equations is done by adjusting coefficients in front of chemical formulas, not by changing subscripts.
