Based on intuition and common sense rather than mathematical rigor it teaches students from scratch using pertinent examples many taken across the physical sciences. Chemical Formula As already stated a chemical formula is a symbolic expression signifying the number of atoms present in a molecular substance. We determine the type of atom by referring to its symbol so for Hydrogen we will use H.
