Question

while looking at xenon (xe) on the periodic table, a student needs to find an element with a smaller atomic mass in the same group. where should the student look?
○ directly up
○ directly down
○ directly to the left
○ directly to the right

In the periodic table, elements in the same group are arranged vertically. Atomic mass generally increases as you go down a group. So, to find an element with a smaller atomic mass in the same group as xenon (Xe), one should look directly up.

Answer:

directly up
