  1. If there only about 100 types of elements in the world, why are there so many different kinds of matter? 60 140 130 120 40 50 30 10 70 8 7 6 5 9 4 3 2 0 180 80 20 90 160 150 170 100 110 1 Seconds Left:

  2. Elements can combine in many different ways to form many different types of matter.

  3. Where are the metals, nonmetals, and metalloids located in the periodic table? 60 140 130 120 40 50 30 10 70 8 7 6 5 9 4 3 2 0 180 80 20 90 160 150 170 100 110 1 Seconds Remaining:

  4. Metals - are on the left side • Nonmetals – are on the right side • Metalloids – are on a slanting line between the metals and nonmetals

  5. Which group of elements on the periodic table does not readily combine with other elements? 60 140 130 120 40 50 30 10 70 8 7 6 5 9 4 3 2 0 180 80 20 90 160 150 170 100 110 1 Seconds Remaining:

  6. Group 18 - the Noble Gasses

  7. Describe metalloids. 60 140 130 120 40 50 30 10 70 8 7 6 5 9 4 3 2 0 180 80 20 90 160 150 170 100 110 1 Seconds Left:

  8. Elements having properties of both metals and nonmetals.

  9. Germanium, with an atomic number of 32, is not a metal or a non-metal, but a metalloid.– Describe where metalloids are found on the periodic table, with respect to the metals and non-metals. 130 120 60 70 40 50 30 10 140 8 7 6 5 9 4 3 2 80 180 20 160 90 150 170 0 100 110 1 Seconds Left:

  10. Metalloids are found in between metals and non-metals on the periodic table. Their position tells us that they have some of the characteristics of metals and some characteristics of non-metals. For example, germanium conducts electricity, but not as well as true metals.

  11. Elements are organized in the periodic table in such a way that there are patterns of elements placed close together that have similar properties. For example, knowing the properties of one element in a column of the periodic table will help a person predict the properties of other elements in that same column.–Describe two properties common to elements found at the far left of the periodic table.–Describe two properties common to elements found at the far right of the periodic table. 60 140 130 120 40 50 30 10 70 8 7 6 5 9 4 3 2 0 180 20 90 160 150 170 80 100 110 1 Seconds Left:

  12. On the far left side of the periodic table the elements are all metals. So, they are solids at room temperature and are good conductors of heat and electricity.One the far right side of the periodic table, the elements are gases at room temperature. They are colorless and non-reactive.
