Question

5. Which of the following conduct electricity the best?

O A silver
OB silicon
O c fluorine
OD arsenic

Answer 1

The answer Silver.
This is because the electrons in this are more free thus making it able to move more and conduct better.

Answer 2

Silver is the best conductor of electricity because it contains a higher number of movable atoms (free electrons). For a material to be a good conductor, the electricity passed through it must be able to move the electrons; the more free electrons in a metal, the greater its conductivity.
