Using the periodic table, which of the following elements is most likely to have similar properties as calcium, and why?
A. Potassium (K), because they are both alkali metals
B. Magnesium (Mg), because they are both alkaline earth metals
C. Scandium (Sc), because they are both in the fourth period
D. Argon (Ar), because they both have three energy levels

For example, group 2 elements are known as alkaline earth metals and magnesium and calcium are same group elements thus, they have same chemical properties.

Thus, we can conclude that using the periodic table, magnesium is the element which is most likely to have similar properties as calcium, because they are both alkaline earth metals.

Option C is correct. the element that is most likely to have similar properties as calcium is Magnesium because they are both alkaline earth metals

Elements in the same group of the periodic table are known to possess similar chemical properties.

Also, the number of the electron in their outermost shell are equal. For instance,

Calcium and Magnesium have 2 electrons in their outermost shell compared to other elements listed.

Moreover, elements in group two of the periodic table are called the alkaline earth metal, hence, the element that is most likely to have similar properties as calcium is Magnesium because they are both alkaline earth metals
