Verified step by step guidance1
Identify the group of elements known as alkaline earth metals. These are found in Group 2 of the periodic table and include elements like Beryllium (Be), Magnesium (Mg), Calcium (Ca), Strontium (Sr), Barium (Ba), and Radium (Ra).
Understand that atomic radius generally increases as you move down a group in the periodic table. This is because each successive element has an additional electron shell, making the atom larger.
Compare the given options with the list of alkaline earth metals. The options provided are Na (Sodium), Ba (Barium), Cl (Chlorine), Mg (Magnesium), and Li (Lithium).
Recognize that among the options, only Ba (Barium) and Mg (Magnesium) are alkaline earth metals.
Determine which of these alkaline earth metals has the largest atomic radius. Since atomic radius increases down the group, Barium (Ba), being lower in the group than Magnesium (Mg), will have the largest atomic radius.
