Question

12 fill in the blank 1 point when comparing magnesium (mg) and phosphorous (p), choose your answer... has a stronger force of attraction between its valence electrons and the protons in the nucleus. this is because both elements choose your answer... and choose your answer... choose your answer... choose your answer...

Explanation:

Step1: Recall periodic trends

Elements in the same period have the same number of electron - shells.

Step2: Analyze nuclear charge

Phosphorus has a higher atomic number (15) than magnesium (12), so it has more protons.

Step3: Determine effective - nuclear charge

With the same number of electron - shells and more protons, phosphorus has a higher effective - nuclear charge, resulting in a stronger attraction between valence electrons and the nucleus.

Answer:

Phosphorus; are in the same period; phosphorus has more protons; a higher effective - nuclear charge
