Interpretation: The reason for the similar chemical and physical properties of magnesium and barium needs to be explained.
Concept Introduction: Elements are arranged in increasing order of
Explanation of Solution
The given elements are magnesium and barium. Here, both elements belong to group 2 in the periodic table. The number of valence electrons in both atoms is 2. They are alkaline earth metals and can donate two electrons to form ions with two positive charges. Due to similar charges on the ions, they can form compounds with the same elements or molecules. For example, both magnesium and barium can combine with one oxygen atom to form their oxides, which are MgO and BaO.
Therefore, as both magnesium and barium belong to the same group in the periodic table, they have similar chemical and physical properties.
