- H represents a hydrogen atom.
- 2H indicates that there are two hydrogen atoms.
- S represents a sulfur atom.
- O represents an oxygen atom.
- 4O indicates that there are four oxygen atoms.
Thus, H2SO4 represents a molecule of sulfuric acid, which consists of two hydrogen atoms, one sulfur atom, and four oxygen atoms.
