For alkali metals, which one of the following trends is incorrect
Options
(a) Hydration energy: Li > Na > K > Rb
(b) Ionization energy: Li > Na > K > Rb
(c) Density: Li< Na < K < Rb
(d) Atomic size: Li < Na < K < Rb
Correct Answer:
Density: Li< Na < K < Rb
Explanation:
Density gradually increases on moving down from Li to Cs. Potassium is, however, lighter than sodium. The abnormal value of potassium is due to unusual increase in atomic size, i.e., atomic volume.
