Answer 1

Answer:

Only 17 elements on the periodic table are nonmetal elements, yet they make up most of the matter in the universe and most of us living things!

Many sources define nonmetal elements as elements that are not metals and lack qualities of metals. What that means is that nonmetal elements are elements with relatively low boiling points, that are poor conductors of heat and electricity, and that do not readily give up their electrons.

In the periodic table below, the nonmetal element squares are colored red. Nonmetals are located on the far right side of the periodic table, except hydrogen, which is located in the top left corner.
