o directly up
o directly down
o directly to the left
o directly to the right

Explanation:

On the periodic table, atomic mass generally increases from left to right across a period. So, to find an element with a greater atomic mass than calcium (Ca) in the same period, the student should look directly to the right.

Answer:

directly to the right
