Which sequence does not correctly arrange the elements in order of increasing energy released (electron affinity) upon formation of its monatomic anion?
A) Ne

Question

Which sequence does not correctly arrange the elements in order of increasing energy released (electron affinity) upon formation of its monatomic anion?
A) Ne < Li < O < Cl
B) Cs < K < Na < Li
C) Be < B < O < F
D) N < C < O < F
E) Mg < Si < S < Ar

Quizplus · Accepted Answer

Ar is a noble gas and does not readily form anions, so it should not be placed after S in terms of increasing electron affinity.
