NOTES FOR METALS, NON-METALS AND METALLOIDS (Page 105) Metals give electrons away Non-metals take or share electrons Metalloids can do either Metals are conductors of heat and electricity Non-metals are insulators. They don’t conduct heat and electricity. Metalloids are semiconductors. They do an OK job of conduction. Metals are found to the left of the staircase on the periodic table. Note that the Lanthanides and the Actinides at the bottom of the table are all metals Non-metals are found to the right of the staircase on the periodic table. Hydrogen is a non-metal even though it’s in the upper left corner. Metalloids are the elements that touch the staircase on the periodic table. Even though Aluminum touches the staircase, it’s still a metal.
