Verified step by step guidance

Identify the position of magnesium (Mg) on the periodic table. Magnesium is in Group 2, which is the alkaline earth metals group.

Understand that elements in the same group (vertical column) of the periodic table generally have similar chemical properties because they have the same number of valence electrons.

Look for the element among the options that is also in Group 2. Calcium (Ca) is in Group 2, while Aluminum (Al), Potassium (K), and Sodium (Na) are in different groups.

Recognize that since calcium (Ca) shares the same group as magnesium (Mg), it will have similar chemical properties, such as forming +2 ions and reacting similarly with other elements.

Conclude that calcium (Ca) is the element most likely to have chemical properties similar to magnesium (Mg) based on their group placement in the periodic table.
