Science quiz: Tuesday

Hypothesize how your classroom would be different if there were no metalloids?

Because metalloids have properties between metals and nonmetals. For example, Silicon is used in almost everything and silicon is a metalloid.

Classify each of the following elements as a metal, a nonmetal, or a metalloid: boron, carbon, aluminum, and silicon?

Carbon: nonmetal Silicon: Metalloid Boron: Metalloid Aluminum: Metal

The ability of a halogen to react with a metal to form a salt is an example of...?

Chemical

An element in group 17 of the periodic table is called an...?

Halogen

Infer which group you would expect to contain 117?

Halogens

Analyze why hydrogen is sometimes classified as a metal.

It gives electrons like a metal does.

Sequence nonmetals, metals and metalloids in order from left to right across the periodic table.

METALS NONMETALS METALLOIDS

An element in group 18 on the periodic table is called an...?

Noble Gas

Distinguish between a nonmetal and a metalloid.

Nonmetal: element that has no metallic properties. Metalloids: elements that has chemical and physical properties of both metals and nonmetals.

Determine whether there would be more nonmetals in group 14 or in group 16.

There would be more nonmetals in group 16.
