Alloy: Mixture composed of two or more elements, at least one of which is a metal.
Chemical formula: Shows the kind and numbers of atoms in the smallest representative unit of substance
Formula unit: The lowest whole-number ration of ions in a ionic compound.
Ionic bond: Electrostatic forces that hold ions together in ionic compounds
Metallic bond: The attraction of the free-floating valence electrons for the positively charged metal ions
Lewis structure: Diagrams that show valence electrons as dots.
Octet rule: Atoms of some non-metals tend to gain electrons or to share electrons with another non-metal to achieve a complete octet
Valence electron: Electrons in the highest occupied energy level of an element´s atom
Ionic compound: Usually composed of metal cations and non-metal anions.
Cation: Atom with a possitive charge
Anion: Atom with a negative charge
