In recent research, strontium ions have been used for bone regeneration within humans as a calcium replacement. Based on your knowledge of periodic information, explain why is strontium a good substitute for calcium instead of other elements on the periodic table. [Hint: think about the way elements are organized based on their common characteristics] *

Strontium, as opposed to other elements on the periodic table (with the exception of others in the same group/column i.e., the vertical direction), is a good substitute for Calcium because they are in the same group.

Explanation:

This is because elements of the same group behave similarly and have similar properties. This is due to the fact that elements of the same group (in the vertical direction) have the same number of valence electrons.

the answer is d. 74.02
