metallic elements and alloys
when a metal reacts with a non-metal during ionic bonding,what happens to the electron on the outer shell of the metal? 
electrons are transferred
how could u describe an ionic compound?
a gaint structure of ions
describe how ionic compounds are held together-string electrostatic forces of attraction between oppositely charged ions
what directions do the forces act in during ionic bonding-all directions in the lattice

2 changes at boiling point - boiling and condensing
2 changes at melting point - melting and freezing
limitation for the model of solids,liquids and gases : no forces, all particles represented as speheres, spheres are solid
