Question

malik analyzed three samples to test which element was a metalloid. the table shows his results. which element (a, b, or c) is most likely a metalloid?

Explanation:

Step1: Recall metalloid properties

Metalloids have intermediate properties between metals and non - metals. They are often lustrous, brittle, have moderate electrical conductivity, and can react with acids or bases.

Step2: Analyze Element A

Element A is lustrous, not brittle, reacts with a base, has a high melting point and high electrical conductivity. These are more like metal properties.

Step3: Analyze Element B

Element B is not lustrous, is brittle, reacts with an acid, has a low boiling point and very low electrical conductivity. These are more like non - metal properties.

Step4: Analyze Element C

Element C is lustrous, brittle, can react with an acid or a base, has a high melting point and medium electrical conductivity. These properties are characteristic of a metalloid.

Answer:

C
