While looking at calcium Ca on the periodic table, a student needs to find an element with a greater atomic mass in the same period. Where should the student look?

Calcium is in period 4, and atomic mass generally increases from left to right across a period. So the student should look directly to the right for an element with a greater atomic mass. “Directly down” is in a different period, not the same one.
