![]() Use your book or information given above to identify these elements. Draw a large circle in the box for the elements that are metalloids. There is no set in stone standard for CPK color schemes, but nearly all molecule kits use the same common CPK colors. Electricity and heat can travel through metalloids but not as easily as they travel through metals. Create a key in the space above the table to identify your colors/groups 1. Halogens green starting light green for fluorine and getting darker as you move down the group. ![]() They can be shiny or dull and their shape is easily changed. are two main groups on the periodic table: metals and nonmetals. The shape of nonmetals cannot be changed easily because they are brittle and will break.Įlements that have properties of both metals and nonmetals are called metalloids. As compared to metals, they have low density and will melt at low temperatures. Their surface is dull and they don’t conduct heat and electricity. phosphorus is a non metal member of group 17 of the periodic table. Using map pencils, color each group on the table as follows: 1. krypton is a noble gas which is a member of group 18 of the periodic table. Your teacher will give you a copy of the periodic table to color. Nonmetals, on the right side of the periodic table, are very different from metals. Student Worksheet This worksheet will help you understand how the periodic table is arranged. ![]() As you move from the left to the right, the elements. Heat and electricity travel easily through metals, which is why it is not wise to stand next to a flagpole during a thunderstorm! Metals and nonmetals The left side of the table contains elements with the greatest metallic properties. Metals will corrode, gradually wearing away, like rusting iron. Their shape can be easily changed into thin wires or sheets without breaking. They are usually shiny, very dense, and only melt at high temperatures. The periodic table on the left separates elements into three groups: the metals (green in the table), nonmetals (orange), and metalloids (blue). They lie along a staircase between the metals and nonmetals. Metalloids are the six or so elements with properties of both metals and nonmetals. What's a molecule? Metals, Nonmetals, & Metalloids As you can see from this color coded version of the Periodic Table, most of the elements are metals.
