3 Main Sections of the Periodic Table Metals Non-metals Metalloids

Metals 1 18 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

Metals: Physical properties Luster = level of shine Malleable = able to be hammered into thin sheets Ductile = able to be pulled into thin wires Good conductors

Metals: Chemical properties Some are very chemically reactive and some are moderately reactive Undergoes corrosion: eating away the metal during a chemical reaction

Non-metals 1 18 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 1 2 3 4 5 6 7

Non-metals: Physical properties Dull Brittle Poor conductors

Non-metals: Chemical properties Most very chemically reactive Group 18 noble gases are not reactive at all

Metalloids 1 18 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

Metalloids: Physical properties Some are shiny and some are dull Brittle but harder Some are good conductors and some are poor

Metalloids: Chemical properties Medium chemical reactivity
