Crystal Lattice

term for an orderly, repeating three-dimensional pattern of many ions, atoms, or molecules

Octet Rule

atoms tend to form bonds so that each atom has 8 electrons in it’s valence shell

metallic compound/bond

• sea of electrons

• highest melting point & boiling points

• solid at room temperature

• conducts electricity when solid & molten

covalent compound/bond

• atoms share electrons

• gas at room temperature

ionic compound/bond

• atoms transfer electrons

• high melting and boiling points

• solid at room temperature

• conducts electricity when a liquid and molten

• soluble in water

volatility

able to be melted/vaporized/boiled easily (opposite of high boiling/melting point)
