Why NaCl has an ionic bond?

Answer 1

All compounds which are can conduct electricity can be used as electrolytes. Since NaCl is an ionic compound and all ionic compounds in aqueous form or molten form can conduct electricity, it can be used as an electrolyte.
The correct formula is NaCL (with the lowercase letter L, not the number 1) and it is an electrolyte.

Answer 2

It can be tough to say what is and what isn't ionic. There are no strict rules and frankly, it's a classification that becomes clearer with experience.

So don't feel bad about it.

As a guideline, bonds are ionic when one atom in the bond is strongly more electronegative than the other. Electronegative atoms are ones at the top right of the table and the effect becomes weaker to the bottom left of the table.

Electronegativity is the power of an element to attract electrons toward it in a covalent bond...when this attraction is seriously one-sided in a bond, we call the bond ionic.

Electronegativity is also a sort of relationship between nucleus charge and atomic radius. Nucleus charge increases you move toward the right on the Periodic Table. Atomic radius decreases as you move up the table. So the top right is most electronegative. Chlorine, Fluorine etc all very electronegative.

Answer 3

It is ionic because the electrons are completely transferred from one atom to another.

Answer 4

NaCl is an anhydrous salt- no water of crystalliation. The ionic nature arises because of the large electronegativity difference between the Na and Cl atoms.

Answer 5

Because Na is sodium-a metal, and Cl is chlorine- a non-metal

Answer 6

Because the difference in electronegativity is large between sodium and chlorine, it is a polar structure.
