Answer: Option (3) is the correct answer.
Explanation:
When a compound dissolved in solution dissociates into ions then the solution is able to conduct electricity is known as an electrolyte.
This means that ionic molecules are able to conduct electricity because they are able to dissociate into ions.
Thus, we can see that out of the given options NaOH is ionic in nature hence, it is an electrolyte.
Whereas ,
, and
are not ionic in nature therefore, they are not electrolyte.
Final answer:
An electrolyte is a substance that produces an electrically conducting solution when dissolved in water. Electrolytes are typically salts that dissociate into ions. Out of the given options, NaOH is an electrolyte as it can dissociate into Na+ and OH- ions. The correct option is 3.
Explanation:
An electrolyte is a substance that produces an electrically conducting solution when dissolved in a polar solvent, such as water. It is typically formed when a salt dissociates into its component ions.
The free ions in the solution interact with the polar solvent (water), allowing the solution to conduct an electric current. In the options given, NaOH(option 3) is considered an electrolyte as it can dissociate into Na+ and OH- ions, thereby allowing the solution to conduct electricity.The correct option is 3.

Ionic compounds are formed by IONS (Obviously, what am I, a dummy?)
There are two types of ions: anions and cations.
Anions can only be formed by nonmetals, and cations can only be formed by metals.
In order for ions to bond, there must be one anion and one cation, because opposite charges attract.
Let's look at your choices.
1) Ca + Br can form ionic bonds
2) Na + F can form ionic bonds
3) Li + Cl can form ionic bonds
However...
4) Mg + Ar
This is a special case. Ar is a NOBLE GAS, which means that it has the maximum number of valence electrons (8) in its outermost shell. Therefore, ANY type of bonding is IMPOSSIBLE.
Your answer should be 4) Mg + Ar
