D. Can conduct electricity and heat

The correct answer is (C)

non- metals have a negative charge when a current is run through its solution.

because the non-metals gain electrons as it has a higher electronegativity

than metals. so non-metals have negative charge in the solution because its

gain electrons and electrons have a negative charge. non-metals are poor

electrical and thermal conductors. example:

S- (sulfur) , He-(Helium), N- (nitrogen)

Answer: Option (C) is the correct answer.

Explanation:

Non-metals are the substances which gain electrons in order to gain stability and hence they form anions.

Some properties of non-metals are as follows.

  • Non-metals are bad conductors of heat and electricity.
  • They are brittle in nature.
  • Non-metals have non-shiny surface.

But non-metals when gain an electron they they acquire a negative charge. Hence, when non-metal is present in ionic form in a solution then it is able to conduct electricity.

Thus, we can conclude that has a negative charge when a current is run through its solution is a characteristic of most non-metals and is not a characteristic of most metals.
