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

Option (B) is the correct answer.

Explanation:

Atoms that have same number of valence electrons are most likely to exhibit similar chemical properties.

So, atoms present in a group will show similar chemical properties.

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.
