Arrange the following according to the instruction given in the bracket:
F, B, N, O (In the increasing order of electron affinity).
A, B, C are three elements in which B is an inert gas other than helium. With this information complete the following table.
| Element | Atomic number | No. of electrons in the valence shell | Group to which the element belongs |
