I think it's Sodium Sulfide, because Na2S contains one Sodium and two Sulfur. Plus Sulfide is used to describe any of three types of chemical compounds that contain sulfur. 

Answer : The correct option is, sodium sulfide

Explanation :

The given formula is, [tex]Na_2S[/tex]

The rules for the naming of the binary molecular compound are :

  • First element in the formula is named first and keep its element name.
  • Gets a prefix if there is a subscript on it.
  • Second element is named second.
  • Use the root of the element name plus suffix (-ide).
  • Always use a prefix on the second element.

In the given formula, the first element is (Na) sodium and the second element is sulfur. Thus, the chemical name of the compound is, sodium sulfide.

Therefore, the chemical name for the compound with the formula [tex]Na_2S[/tex] is, sodium sulfide.
