describe the trends in atomic radii by checking the correct box. atomic radii from the left to right across a period tend to: increase. decrease. atomic radii from the top to the bottom of a group tend to: increase. decrease. done
Answer
Brief Explanations:
As you move from left to right across a period, the number of protons increases, pulling electrons closer, thus atomic radii decrease. As you move from top to bottom in a group, new electron - shells are added, increasing the atomic radius.
Answer:
Atomic radii from the left to right across a period tend to: decrease. Atomic radii from the top to the bottom of a group tend to: increase.
