Molecular formula explained
Molecular Formula Definition - Chemistry Glossary
A molecular formula shows the arrangement of the atoms in a molecule. ... One model of molecular bonding pictures a molecular orbital that is a combination of individual atomic orbitals. ... Information about the kind and shape of the bonds is explained by hybridization. Hybrid orbitals can form with single, double, or triple covalent bonds. ...
