# What Is the Charge on the Cation in the Ionic Compound Sodium Sulfide??

Contents

And thus the chemical formula for sodium sulfide is #Na_2S#, i.e. two sodium ions are required to form a neutral salt with #S^(2-)#.

## What is the cation in sodium sulfide?

Formula and structure: The sodium sulfide formula is Na 2 S the molar mass is 78.0452 g mol – 1. The salt also has a hydrated form 240.18 g mol – 1 The molecule is formed by two sodium cations Na + and one sulfur anion – 2.

## What is the charge for sodium sulfide?

The chemical symbol or chemical representation of sodium is Na and the sulfide ion is having a charge of -2.

## What is the cation charge of sodium?

A sodium atom can lose its outer electron. It will still have 11 positive protons but only 10 negative electrons. So, the overall charge is +1. A positive sign is added to the symbol for sodium, Na +.

A cation is formed when a neutral atom loses electrons and becomes positively charged. On the other hand, an anion is a result of a neutral atom gaining electrons and becoming negatively charged. A cation and anion attract each other and establish an ionic compound. This bond leads to the formation of an ionic compound.

Sulfur is capable of gaining 2 electrons forming the anion sulfide, {eq}\rm S^{2-}
{/eq}.

## Explanation:

And thus the chemical formula for sodium sulfide is

## Ionic Compounds:

A cation is formed when a neutral atom loses electrons and becomes positively charged. On the other hand, an anion is a result of a neutral atom gaining electrons and becoming negatively charged. A cation and anion attract each other and establish an ionic compound. This bond leads to the formation of an ionic compound.

## Answer and Explanation: 1

Sodium, {eq}\rm Na {/eq}, is a metallic element. Being a metal, it tends to lose an electron forming a cation. For sodium, it loses one electron and becomes the cation sodium ion, {eq}\rm Na^+ {/eq}. On the other hand, sulfur, {eq}\rm S {/eq}, is a nonmetallic element that tends to gain electrons and form an anion. Sulfur is capable of gaining 2 electrons forming the anion sulfide, {eq}\rm S^{2-} {/eq}.The chemical formula of an ionic compound is written by using the chemical symbols of the ionic species. Moreover, the subscript written after the chemical symbol of an ion is obtained from the magnitude of the charge of the opposite ion. A sodium ion has a charge of magnitude 1 while sulfide has a charge of magnitude 2. Thus, the chemical formula of sodium sulfide is {eq}\rm Na_2S {/eq}.Note that the absence of a subscript after {eq}\rm {/eq} indicates a value of 1.
