ICSE Class 10 Answered

which metal has most electron affinity and which has least and why? Na, K, Li, or Cs
Asked by saibaba1069 | 23 Apr, 2020, 12:42: AM
Expert Answer
Electron affinity decreases down the group as the atomic size increases. Due to which the electron is added further away from the nucleus and electron affinity decreases.
 
Thus the order is Li > Na > K> Cs
