Metals are good conductors of heat and electricity. They can be malleable (molded) and ductile (stretched). Metals have high melting and boiling points.
Metallic bonds are the electrostatic attraction between metal ions arranged in a lattice structure with free flowing electrons.

Describe the structure of atoms in terms of electron shells
Basic structure of the atom. Note the charges of the proton, neutrons and electrons:
Electron shells accommodate different numbers of electrons. The electron configurations for the first 20 electrons is explained below:
Isotopes are atoms with the same number of protons but different numbers of neutrons. Many elements have naturally occurring isotopes, however, one isotope is usually much more abundant than the others.
An ion is an atom or molecule that carries an electric charge.
Ionic bonding is an electrostatic attraction that involves the complete transfer of electrons from one atom to another.
Mass is neither created nor destroyed in a chemical reaction
