Q 6 (b) Arrange the elements of second period in increasing order
of their electron affinity Name the elements which do not follow
the trend in this period

Raveena Sharma · Accepted Answer

Electron affinity is the energy released when an electron is added to an isolated gaseous atom
 In the periodic table EA value increases when me move from left to right
 The value is 0 or very low, when an electron is added to a stable electronic configuration
 (Half filled and fully filled orbitals)
 In the second period Be, N and Ne has zero electron affinity value
 Ne<Be<N < B < Li < C < O < F-29 < -19 < -7 < 27 < 60 <122 < 141 < 328 (kJ/mol)The reason of low electron affinity value of Ne is due to 2s22p6 configurationThe reason of low electron affinity value of Be is due to 2s2 configurationThe reason of low electron affinity value of N is due to half filled  2s22p3
