– They are grouped into metals, nonmetals, and metalloids
– exception is hydrogen, it is on the top left
– Malleability: Many metals can be molded or stretched into sheets when heated. Most are ductile which means they can be pulled into wires.
– Conductivity: Heat and electricity flow easily through most metals (they are conductors). Use metals for cookware because heat can transfer through the pan to cook the food.
– Malleability: Usually more brittle than metals. They cannot be molded or stretched. If dropped or hit with a hammer it will break. Many are gases at room temperature
-Conductivity: Nonmetals do not allow either heat or electricity to flow through them easily. (they are insulators). Air is a mixture of nonmetal gases. For this reason air pockets are built into jackets and other objects that are intended to keep people warm.
-Malleability: Can be malleable (stretched/molded) or ductile (pulled into wires) like metals or brittle like nonmetals
-Conductivity: They have intermediate heat and electrical conductivity. They do not conduct as effectively as metals, but they are not insulators like nonmetals.
– Because electricity can be controlled better, they are used in a lot of electronics. Used to make computer chips.
