sodium sulfide , the constiuent element is sodium and sulphur

Answer 2

Name of the compound is Sodium sulfide

Explanation:

• the compound formed from the given atomic formula Na2S is Sodium sulphide.

• The constituent elements are represented by their chemical symbols.

• and the names of the constituent elements used are sodium (Na) and sulphur (S).

• the valency of sodium (Na) is 1 and the valency of sulphur(S) is 2.

• the required chemical equation becomes: 2 Na + S → Na2S.

• In the chemical equation 2Na + S → Na2S, there are 2 sodium atoms and 1 Sulphur atom.

hence, The Name of the compound is Sodium sulfide and names of the constituent elements are Sodium(Na) And Sulphur (S).
