which of the following is favorable condition for the formation of ionic bond A. 0 B. 1 C .3 D. 4
1 is the correct answer.
For ionic bonds, the atoms must be bounded together by ellectrostatic force in attaraction between ions of opposite charges.
You can say of NaCl . NaCl is an ionic bond of Sodium metal and Chlorine non-metal. It forms the strongest bond and is ionic in nature.
Ionic bond is just a very strong electrostatic force of attraction between cation and anion.
Cation is positively charged species and metals are electropositive in nature. They tend to donote ions.
Anions are negatively charged ions and non-metals are electronegative in nature. They tend to gain ions.
