Question

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

Explanation:

In the periodic table, elements in the same period are arranged from left - to - right with increasing atomic number and generally increasing atomic mass. So to find an element with a greater atomic mass in the same period as calcium, one should look directly to the right.

Answer:

directly to the right
