Question
Favourable condition for formation of an ionic bond is/are Low ionisation energy of the metal High electron affinity of non-metal High lattice energy of ionic compound All of these
Solution
The formation of an ionic bond is favored by the following conditions:
-
Low ionization energy of the metal: Ionization energy is the energy required to remove an electron from an atom. Metals, which typically form the positive ions in ionic compounds, have low ionization energies. This means they can easily lose electrons to form positive ions.
-
High electron affinity of the non-metal: Electron affinity is a measure of how much an atom wants to gain an electron. Non-metals, which typically form the negative ions in ionic compounds, have high electron affinities. This means they can easily gain electrons to form negative ions.
-
High lattice energy of the ionic compound: Lattice energy is a measure of the strength of the forces between the ions in an ionic compound. A high lattice energy means the ions are strongly attracted to each other, which makes the compound more stable.
So, the answer is "All of these". All these conditions favor the formation of an ionic bond.
