Question

9 fill in the blank 1 point when comparing the ionization energies between phosphorus and magnesium choose your answer... has higher ionization energy. this is because phosphorous has choose your answer... attraction between the valence electron and the protons thus requiring more energy to choose your answer...

Explanation:

Step1: Recall ionization - energy concept

Ionization energy is the energy required to remove an electron from an atom.

Step2: Analyze nuclear - electron attraction

Phosphorus has a greater nuclear charge and a smaller atomic radius compared to Magnesium. So, there is a stronger attraction between the valence electron and the protons in Phosphorus.

Step3: Determine the answer

Since Phosphorus has a stronger attraction, it requires more energy to remove a valence electron.

Answer:

1. Phosphorus
2. stronger
3. remove a valence electron
