Predict the order of increasing ionic radius for each of the following sets of elements.Use the element symbols and make sure you use correct capitalization.  If there is a charge place the sign then the number without using spaces.  Example:  Ca+2 or F-1 A)    Mg+2, Ca+2, Ba+2Smallest to Largest

To predict the order of increasing ionic radius for the given set of elements (Mg+2, Ca+2, Ba+2), we need to consider the periodic trends.

1. The ionic radius generally increases as we move down a group in the periodic table. This is because the number of electron shells increases, resulting in a larger atomic size.

2. Among the given elements (Mg+2, Ca+2, Ba+2), they all belong to Group 2 (or Group IIA) of the periodic table, also known as the alkaline earth metals.

3. Since all the elements have a +2 charge, we can compare their ionic radii based on their atomic sizes.

4. In this case, the order of increasing ionic radius would be from smallest to largest: Mg+2, Ca+2, Ba+2.

Therefore, the correct order of increasing ionic radius for the given set of elements is: Mg+2 < Ca+2 < Ba+2.
