write the favourable factors for the formation of ionic bond.
Answers
Ionic bond is a type of chemical bond which involves the transfer of one or more electrons from one ion to another ions of opposite charges.The ion which gains an electron is called as anions, whereas the ion which has loose an electron is called as cation.Mostly the cations are metals & anions are non metal.
Hence, favourable factors for ionic bond formation are as follows:
(i) Low ionization enthalpy of metal atom.
(ii) The two ion must be different & should possess opposite charge
(iii) High electron gain enthalpy (Δeg H) of a non-metal atom.
(iv) High lattice energy of the compound formed.
(v) The electron negativity between two ions should be greater
(i) Low ionization enthalpy of element forming cation. (ii) More negative electron gain enthalpy of element forming anion.
