Question

1pt which of the following is true about metals?

a. mostly solids, luster, high density, conductors

b. mostly gases, brittle, dull, low density, insulators

c. solids, luster, brittle, conductors, medium density

d. mostly solids, dull, brittle, reactive, conductors

Explanation:

Metals are typically solids (except mercury), have a luster (shine), high density, and are good conductors of heat and electricity. Option B is incorrect as metals are not mostly gases. Option C is wrong because metals are not brittle (they are malleable and ductile). Option D is incorrect as metals do not have a dull appearance (they have luster) and are not brittle.

Answer:

A. mostly solids, luster, high density, conductors
