The ionisation potential order for which set is correct?

Options

  1. ACs Li K
  2. BCs Li B
  3. CLi K Cs
  4. DB Li K

Correct answer

C. Li K Cs

Step-by-step solution

The ionisation potential decreases down the group (due to increase in size of atom) and increases in a period from left to right. Out of the given choices Li K Cs is correct.
