Answer
Both A and R are true and R is the correct explanation of A.
Explanation — The anion is formed easily if the electron affinity value is high. A high (more negative) electron affinity means an atom releases a significant amount of energy when it gains an electron indicating it strongly attracts electrons. This makes it easier for the atom to accept an electron and form a negative ion (anion). Hence the Assertion (A) is true.
Electron affinity encourages electron acceptance, which is a step in ionic bond formation. Hence Reason (R) is also true and it correctly explains Assertion (A).
