Question

Illustrate how sodium sulfide (Na₂S) is formed.

Answer 1

• Chemical Accuracy: The explanation accurately details how two sodium atoms each lose one valence electron to form $\text{Na}^+$ ions, sulfur gains those two electrons to form the sulfide ion ($\text{S}^{2-}$), and the oppositely charged ions combine via electrostatic attraction to form sodium sulfide ($\text{Na}_2\text{S}$).
• Equations: The electronic configuration steps and ion combination equations are scientifically sound and properly balanced.
