3. Draw the Lewis symbols for each of the following elements, both before and after the reaction to obtain a complete shell:

Before reaction:
- Br
- S

After reaction:
- Br
- S

Write a chemical equation showing the transfer of electrons from sodium atoms to sulfur atoms to produce sodium sulfide.



Answer :

GinnyAnswer

Final answer:

Lewis symbols represent valence electrons, the reaction of sodium with sulfur forms sodium sulfide through electron transfer.


Explanation:

To draw Lewis symbols for elements, place dots representing valence electrons around the chemical symbol. For sulfur with 6 valence electrons, the Lewis symbol is S with 6 dots. After reaction with sodium to form sodium sulfide, the transfer of electrons results in an ionic compound where each symbol represents its respective charge. The chemical equation for the reaction of sodium with sulfur to produce sodium sulfide is: 2Na + S -> Na2S. In this reaction, sodium atoms transfer electrons to sulfur atoms.
