Question

The outermost electronic configuration of the most electronegative element is

• A. $ n{{s}^{2}}n{{p}^{3}} $
• B. $ n{{s}^{2}}n{{p}^{4}} $
• C. $ n{{s}^{2}}n{{p}^{5}} $
• D. $ n{{s}^{2}}n{{p}^{6}} $

Answer 1

Answer: (C)

$ n{{s}^{2}}n{{p}^{5}} $ configuration represents the most electronegative element as after gaining one electron it becomes more stable (inert, gas configuration) [electronegativity is the tendency of attracting electron].
