Ionic bonds are formed due to electrostatic force of attraction and Ionic compounds exist as the crystal lattice, (combination of billions of ions), so ionic bond is very strong bond and requires high amount of heat for decomposition.
But in water ionic bonds are weak and easily decompose into ions.
Example.
NaCl ------------ 801 0C----------> Na1+ + Cl1-
NaCl--- water + room temp.---->Na1+ + Cl1-
Ionic bond.
In ionic compounds, there are strong attractions among the ions; therefore it takes a lot of energy to break those bonds.High melting point depends on bond strength. When talking about bond strength in ionic compounds, I mean lattice energy. So the easiest answer is: They have a high lattice energy.The strong electrostatic interactions between ions require a lot of energy to break the bonds.
KBr
NaCl is ionic.
Yes, all sodium compounds are ionic.
The more lattice energy there is, the more the ionic bond attracts electrons from other atoms forming new compounds.
These are melting point, boiling point, hardness.
It depends what kind of bond. A covalent bond is barely affected at all. The strength of an ionic bond is essentially reduced to nothing because ionic compounds dissolve readily in water, which breaks all the ionic bonds.
Ionic bonding forms compounds.
Ionic bond.
covalent compounds have weaker bonds than those of ionic.
Ionic compounds do not show malleablity.
