For example, as we just saw, the chemical formula for acetic acid is C, Chemical formulas only tell us how many atoms of each element are present in a molecule, but structural formulas also give information about how the atoms are connected in space. However, if another oxygen atom is added a new compound called Hydrogen Peroxide is created - H2O2 which indicates that 2 atoms of Hydrogen combines with 2 atoms of oxygen thus creating the compound Hydrogen Peroxide. Thus Ge is probably a covalent solid.
