Question

Which statement BEST compares the properties of silicon (Si) and nickel (Ni)?
A
Silicon is brittle, while nickel is malleable.
B
Silicon is ductile, while nickel is not ductile.
C
Silicon is a good conductor of electricity, while nickel is not.
D
Silicon is liquid at room temperature, while nickel is solid at room temperature.

Answer 1

The statement that BEST compares the properties of silicon (Si) and nickel (Ni) is:

A. Silicon is brittle, while nickel is malleable.

This is an accurate comparison of their physical properties: silicon, a non-metal, is indeed brittle, while nickel, a metal, is known for its malleability and ductility.
