Atomic Theory P2

Organization Of The Periodic Table / Particles

Valence Electrons The electrons fire this farthest from the nucleus ; they responsible for atoms forming compounds
Molecule 2 or more atoms chemically combined
Compounds 2 different atoms chemically combined
Mixture A combined of 2 or more different atoms or molecules that are not chemically combined
Covalent Bonds Chemical bond between 2 non-metals
Ionic Bond Chemical bond between a metal and non-metal
Octet Rule Elements are stable when their valence shell is full. T'his can be done with 8 or in some cases 2
Alkali Metals Reactive to water also they have 1 valence electrons
Alkali Earth Metals Reactive to water also they have 2 valence electrons
Transitions Reactive to acid to form metal salts, carbon dioxide, and water also most transition metals have 2 valence electrons
Halogens All halogens are reactive to hydrogen also they have 7 valence electrons
Inert Gases Reactive to helium (2 valence electrons) and have 8 valence electrons
