Questions & Step-by-Step Solutions
Which of the following elements would you expect to have the largest atomic radius?
Step 1: Understand what atomic radius means. Atomic radius is the size of an atom, usually measured from the nucleus to the outermost electron shell.
Step 2: Know that atomic radius generally increases as you move down a group in the periodic table. This is because each element down a group has an additional electron shell.
Step 3: Look at the elements given in the question. Identify their positions in the periodic table.
Step 4: Determine which element has the most electron shells. The more shells an element has, the larger its atomic radius.
Step 5: Conclude that Rubidium, being lower in the periodic table compared to the other options, has the most electron shells and therefore the largest atomic radius.
