Given below are atomic radii of same elements of second **.
| Element | B | O | N | C | | ,Atomic Radii in pm | 88 | 66 | 74 | 77 |
Arrange these elements in the increasing order of their atomic number. Give reason for your answer.
B, C, N, O.
In a **, as the atomic number increases, the size of the atom decreases. This is because of increase in nuclear charge tends to pull electrons, closer to nucleus and reduces the size of the atom.
