·       Highly reactive

·       3 energy levels

·       1 valence electron

·       Good conductor

Which element do these characteristics most likely describe?

• phosphorus

• bromine

• sodium

Which of the following statements is true concerning the circled elements?

• They are metals

• They are non-metals

• They are rare earth metals

• They are metalloids

Which of the following statements is NOT true of krypton, argon and neon?

• They are inert

• They are noble gases

In a lab experiment, students had four samples of elements. They made observations about the appearance of each sample, then proceeded to conduct three separate experiments. In the first, they found the melting point of each by holding small samples in a Bunsen burner with a temperature probe. In the second, they held a conductivity probe to two separate sections of the sample. In the final test, they took a small sample and hit it with a hammer.

Which element is LEAST likely to be metallic?

• Substance A

• Substance B

• Substance C

• Substance D

• It is a metal, has 7 valence electrons, and is conductive.

Which of the following statements is true concerning all metalloids?

• They are extremely reactive
