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

Explanation:

In the periodic table, elements in the same period (horizontal row) have atomic number increasing from left to right. Atomic mass generally increases with atomic number in a period. So, to find an element with greater atomic mass in the same period as calcium (Ca), we look directly to the right.

Answer:

directly to the right
