1 METALS, NONMETALS, and METALLOIDS

2 WHAT DOES THE ZIG ZAG LINE DO?

3 The Zig Zag line…. ….separates the metals and the nonmetals. …. is where you find the metalloids.

4 WHAT ELEMENTS MAKE UP THE MAJORITY OF THE PERIODIC TABLE?

5

6 WHERE ARE THE METALS LOCATED?

8 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! AlAl MZMZ

9 WHAT ARE SOME PROPERTIES OF METALS?

10 Properties of Metals Shiny and silvery

11

12 Properties of Metals Shiny and silvery Hard, Malleable, Ductile

13 HARD

14 MALLEABLE

15 DUCTILE

16 Properties of Metals Shiny and silvery Hard, Malleable, Ductile High Melting Points

17 HIGHEST

18 1200 Degrees to melt Silver!

19 Properties of Metals Shiny and silvery Hard, Malleable, Ductile High Melting Points Good thermal conductors

25 WHERE ARE THE NON-METALS LOCATED?

26 INERT GASES INCLUDED

27 WHAT ARE SOME PROPERTIES OF THE NON-METALS?

28 Non-metals have properties opposite of the metals

29 Opposite of the metals Dull or transparent

30

31 Opposite of the metals Dull or transparent Fragile (not strong)

32 Not strong

33 Opposite of the metals Dull or transparent Fragile (not strong) Low melting points

34 LOWEST

35 Opposite of the metals Dull or transparent Fragile (not strong) Low melting points Bad conductors Low Density

36 POOR CONDUCTORS

37 WHERE ARE THE METALLOIDS AND WHAT ARE THEIR PROPERTIES?

38 Metalloids Are between the metals and the non- metals They sometimes have properties like metals and sometimes like non- metals. A veces tienen propiedades de los metales y a veces como los no metales

39 Check for understanding Divide the characteristics and examples into 3 groups MetalsNon-metalsMetalloids
