METALS, NONMETALS, and METALLOIDS WHAT DOES THE ZIG ZAG LINE DO? The Zig Zag line…. ….separates the metals and the nonmetals. …. is where you find the metalloids. WHAT ELEMENTS MAKE UP THE MAJORITY OF THE PERIODIC TABLE? WHERE ARE THE METALS LOCATED? SCAVENGER HUNT Fold your paper in half (hot dog style) Put letters A – M on the left side Put letters N – Z on the right side See if you can find an object made of metal for each letter of the alphabet Objects can be on your body, in your backpack, or in the classroom GO!

Properties of Metals Shiny and silvery Hard, Malleable, Ductile High Melting Points Good thermal conductors Properties of Metals Shiny and silvery Hard, Malleable, Ductile High Melting Points Good thermal conductors Good electrical conductors WHERE ARE THE NON-METALS LOCATED? INERT GASES INCLUDED WHAT ARE SOME PROPERTIES OF THE NON-METALS? Non-metals have properties opposite of the metals Opposite of the metals Dull or transparent Opposite of the metals Dull or transparent Fragile (not strong) Opposite of the metals Dull or transparent Fragile (not strong) Low melting points Opposite of the metals Dull or transparent Fragile (not strong) Low melting points Bad conductors Low Density WHERE ARE THE METALLOIDS AND WHAT ARE THEIR PROPERTIES? Metalloids Are between the metals and the nonmetals They sometimes have properties like metals and sometimes like nonmetals.
