Document Summary

Compounds are made up of atoms held together by chemical bonds. Chemical bonds are a result of interactions between the charged particles electrons and protons that compose the atoms. Between metals and nonmetals involve a transfer of electrons from one atom to another formed by the attraction of oppositely charged ions (cation and anion) by electrostatic forces: covalent bonds. Between 2 or more nonmetals involve sharing of electrons between 2 atoms the shared electrons interact with the nuclei of both atoms, lowering the potential energy of the system through electrostatic interactions and forming a covalent bond. Most stable configuration = lowest potential energy. Empirical formula: gives relative number of atoms of each element in a compound. Molecular formula: gives the actual number of atoms of each element in a compound. Structural formula: uses lines to represent covalent bonds and shows how atoms in a molecule are connected or bonded to each other.
