Answer:
C) 7 to 1
Explanation:
The periodic trend of Atomic Radii for the Periodic Table of Elements is down and to the left the atomic radii increases.
So, from period 1 to 7 and group 18 to group 1, the atomic radii increases.
The opposite (decreasing) would be from period 7 to 1 and group 1 to group 18.
Therefore, our answer is C.
D is the correct answer.
The trend that follows a group (vertical lines) is that they each contain the same number of valence (outer) electrons
