Question

what is an iconic bond? what are the condition for formation of iconic bond.​

Answer 1

Answer:

The Condition required for the formation of an ionic bond between two Elements are: Two elements must be of opposite charge. An element must have its less Ionisation Enthalpy(Cation). Another element must have high negative electron gain enthalpy(Anion).

Answer 2

Answer:

For the formation of ionic bond, the two atoms taking part in bond formation must have opposite behavior. The conditions are the following:

(1) One of the atoms must be a metal and the other must be a non-metal.

(2) The two atoms must be positioned very far away in the periodic table. The metal atom must be on the very left side and the non-metal atom must be on the very right side of the periodic table, so that:

(3) the metal atom has very low ionization energy so that it loses electrons easily to form cations (+ charged ions). In other words, the metal atom must be highly electropositive.

(4) the non-metal atom must have very high ionization energy or very high electron affinity, so that it easily attracts electrons (from the metal) and forms anions (- charged ions). In other words, the non-metal atom must be highly electronegative.

The bond is “considered to be” ionic if the difference in electronegativity between the two atoms is greater than 1.5

If the atoms are positioned nearby in the periodic table (or are of the same type; both metal or both non-metal), they usually form covalent bonds.
