Final answer:
To find an element with a greater atomic mass in the same period as calcium, the student should look to the right.
Step-by-step explanation:
In the same period of the periodic table, elements have the same number of energy levels. The atomic mass increases from left to right across a period. Therefore, to find an element with a greater atomic mass in the same period as calcium (Ca), the student should look to the right of calcium.
