Outliers are data points that fall way off the average range of values in a dataset. In this case, the number 13 is way off from the

Why? I can't explain. I Just left class where they were just explaining that.
Answer:
Atomic radii vary in a predictable way across the periodic table. As can be seen in the figures below, the atomic radius increases from top to bottom in a group, and decreases from left to right across a period. Thus, helium is the smallest element, and francium is the largest.
