which element has the largest atomic radius? consider each elements electronegativity and the number of energy levels it has. aluminum, al sodium, na magnesium, mg

Answer

Brief Explanations:

Atomic radius generally decreases across a period (from left to right) on the periodic table. This is because as you move across a period, the number of protons in the nucleus increases, leading to a stronger effective nuclear charge that pulls the electrons closer to the nucleus. Sodium (Na), Magnesium (Mg), and Aluminum (Al) are all in Period 3. Sodium is in Group 1, Magnesium is in Group 2, and Aluminum is in Group 13. Following the trend, the element furthest to the left in the period will have the largest atomic radius. Therefore, Sodium (Na) has the largest atomic radius among the three.

Answer:

sodium, Na
