Verified step by step guidance1
Understand that elements in the same group (vertical column) of the periodic table have similar chemical properties because they have the same number of valence electrons.
Identify the group of calcium (Ca) in the periodic table. Calcium is in Group 2, which is the alkaline earth metals group.
Look for the element among the options that is also in Group 2. Chlorine is in Group 17, Sodium is in Group 1, Aluminum is in Group 13, and Strontium is in Group 2.
Since Strontium is in the same group as Calcium, it has similar chemical properties due to having the same number of valence electrons.
Therefore, the element with chemical properties most similar to calcium is Strontium.
