Problem: Using only the periodic table, rank the following elements in order of increasing ionization energy: Br, F, Ga, K, and Se.

FREE Expert Solution

Ionization energy is the energy required to remove an electron from a gaseous atom or ion.

The trend of the ionization energies of the elements can be observed in the periodic table:

increases going from left to right of a period

decreases going down a group



Let’s check their location in the periodic table and see how they fall in the trend mentioned.
