11. arrange the following elements in order from smallest ionization energy to largest ionization energy. periodic table smallest ionization energy → largest ionization energy a b c choices: li cs k

Answer

Explanation:

Step1: Recall ionization - energy trend

Ionization energy increases across a period and decreases down a group in the periodic table. Li, K, and Cs are all in Group 1 (alkali - metals).

Step2: Determine the order

Since ionization energy decreases down a group, and Cs is the bottom - most among Li, K, and Cs, Cs has the smallest ionization energy. K is below Li but above Cs in the group, and Li is the top - most, so Li has the largest ionization energy.

Answer:

A. Cs, B. K, C. Li
