What periodic trend does the atomic radius follow?A.It increases from left to right.B.It decreases from top to bottom.C.It decreases from left to right.D.It stays the same across the table.SUBMITarrow_backPREVIOUS
Solution
The atomic radius follows the trend C. It decreases from left to right. This is because as you move from left to right across a period, the number of protons in the nucleus increases, which pulls the electrons in closer to the nucleus, thus decreasing the atomic radius.
