Answer 1

Calcium, Ca

Step-by-step explanation:

Answer 2

Calcium(Ca)

Step-by-step explanation:

• Atomic radius is the distance from the nucleus of an atom the outermost energy shell or energy level.
• The atomic radii of metals are greater than the ionic radii since metals form ions by losing electrons.
• Calcium atom has a larger atomic radius compared to magnesium atom because it has more energy levels. Calcium atoms have four energy levels while magnesium atoms have three energy levels.
