1. METALS, NONMETALS, & METALLOIDS PERIODIC TABLE

2. METALS Good conductors of heat and electricity All, but Mercury (Hg), are solid at room temperature Metals are located to the left of the staircase

3. Group 2 metals Shiny Ductile Malleable Combine readily with other elements Group 1 metals Most reactive of all metals Don’t occur in nature in their element form METALS Alkali MetalsAlkaline Earth Metals

4. Lanthanide Series – Elements 57-71 Actinide Series – Elements 89-103 Groups 3-12 Most familiar metals because they often occur in nature uncombined with other substances Transition MetalsRare Earth Metals

5. NONMETALS Elements that are usually gases or brittle solids at room temperature Most can form ionic & covalent compounds Located to the right of the staircase

6. NOBLE GASES Group 18 elements Exist as isolated atoms They are all stable because their outer energy levels (shells) are full

7. METALLOIDS Elements that make up the stair steps These elements have both metallic & non-metallic properties Used in technology (cell phones, computers, microchips, etc.) Metalloids are part of the mixed groups which contain metals, non-metals, and metalloids Mixed groups are Groups 13, 14, 15, 16, & 17
