Question

Which one of the following will react most vigorously with water? (A) Li (B) K (C) Rb (D) Na

Tardigrade Admin · Accepted Answer

Reactivity with water increases on moving down the Goup from Li to Cs as Li < Na < K < Rb < Cs. This is due to increase in electropositive character. Hence Rb reacts most vigorously with wate
