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. 9 8 10 20 30 7 5 2 3 4

12. On the far left side of the periodic table the elements are all metals
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.
