Arrange the elements oxygen, sulfur, tellurium, and selenium in order of increasing atomic radii. Is your order an example of a group trend or a period trend?
a group trend. $\operatorname{oxygen}\left(_{8} \mathrm{O}\right) \rightarrow$ sulfur $(16 \mathrm{S})$$\rightarrow$ selenium $\left(_{34} \mathrm{Se}\right) \rightarrow$ tellurium $\left(\mathrm{s}_{2} Te) \right.$

in this pressure were us. Prepare oxygen, sulfur to Leary and selenium according to their atomic radius. If we find these elements on the periodic table, we find that they all belong to Group 16. This is because they're all in the same column On the periodic table. Columns are the groups and periods air the robes. So Group 16 contains the following elements. Atomic Radius increases as me go down a group of increasing atomic radius as we go down the group, which means that's a delirium has the greatest atomic radiance. So we were to drink thes from, um, least two greatest atomic radius. We would say that oxygen smart Salford. This more than Cellini. Um, you finally delirium his greatest in service. This is a group trend because all of these elements belong to the scene.
