Why Does Gallium Have A Low Ionization Energy?

Why Does Gallium Have A Low Ionization Energy? According to periodic table, the elements Zinc, Gallium, and Potassium belongs to 4th period. But the ionization energy of gallium is lower than zinc because Zinc has a completely filled electronic configuration whereas gallium which starts filling p-orbitals . What is the ionization energy of gallium? 10)

Why Is The Ionization Energy Of Phosphorus Lower Than Nitrogen?

Why Is The Ionization Energy Of Phosphorus Lower Than Nitrogen? Answer: Well, it is for the same reason nitrogen atom has a higher first ionization energy than oxygen atom. Since the 3p electrons in sulfur (that sulfur would lose) are paired, sulfur has more electron repulsion in those orbitals than phosphorus does, so it takes
