Question

The tendency of losing electron(s) to form cation(s) (or) gaining electron to form anion(s) depends on
the following factors.
i) Atomic size
ii) Ionisation potential iii) Electron affinity iv)Electronegativity
a)What are the favourable conditions for the formation of anion ?
b)The atoms of elements with high I.E, Electron affinity, small size of atom, high electronegative form.​

Answer 1

Answer:

i) An electropositive element loses an electron to form cation. Na is one such element, which forms Na+ cation.

(ii) An electronegative element gains an electron to form an anion. Cl is one such element, which forms Cl− anion.

The Condition required for the formation of an ionic bond between two Elements are: The two elements must be of opposite charge, one negatively charged (anion) and the other positively charge (cation). One of these elements must have high negative electron gain enthalpy(Anion).
