Which element is most likely to be shiny? sulfur (s) boron (b) calcium (ca) carbon (c)

Option (c) is the correct answer.

Explanation:

Metals are the substances which have excess of electrons. They have shiny surface and metals are good conductors of heat and electricity.

Whereas non-metals are electron deficient in nature and they are brittle and ductile.

In the given options, sulfur, boron and carbon are non-metals. Hence, they are  not shiny. Whereas calcium is a metal.

Therefore, we can conclude that calcium is the element which is most likely to be shiny.
