Correct Answer
C Chlorine
D Magnesium
Correct Answer

Option B is the correct answer.

Detailed Explanation

Ionization energy generally increases across a period from left to right. Period 3 begins with sodium (Na) on the far left, which has the lowest ionization energy in the period because it has only one valence electron that is easily removed.

Hint

Think about the periodic trend. Which element is farthest to the left in Period 3?
