Chapter 6: Q6.13CYL (page 326)

Which has the lowest value for IE1: O, Po, Pb, or Ba?

Short Answer

Expert verified

Ba has the lowest first ionization energy.

Step by step solution

01

Step 1:Trends in ionisation energy

Ionization energy increases from bottom to top in a periodic table due to decrease in atomic size.

Ionization energy increases as we move from left to right in a periodic table due to decrease in atomic size of the respective elements.

02

Explanation

Based on the positions of the elements in the periodic table, we can observe that Ba is farthest left and farthest down in the periodic table. Hence, Ba-atom is larger in size.

Thus, Ba-atom has the lowest ionization energy.
