Question

25/35 which has a lower ionization energy: lithium or potassium? lithium potassium

Explanation:

Ionization energy generally decreases as we move down a group in the periodic table. Lithium (Li) and Potassium (K) are both in Group 1 (alkali metals). Potassium is below Lithium in the periodic table, meaning its outermost electron is further from the nucleus and experiences more shielding. This makes it easier to remove the electron, so Potassium has a lower ionization energy.

Answer:

Potassium
