Chemistry Question on p -Block Elements
Elements of which of the following groups will form anions most readily?
A
Oxygen family
B
Nitrogen family
C
Halogens
D
Alkali metals
Answer
Halogens
Explanation
Solution
Halogens have maximum electron gain enthalpy as their atoms have just one electron less than the stable noble gas configuration (ns2np6). Hence, halogenshave the maximum tendency to accept the electron to form a negative ion (anion).
Therefore, option (c) is correct as halogens have the highest electronegativity.
