Question

Which elements are included in Group 5A? Se, Te, Po Rb, Xe Sn, Pb N, P, Bi

Answer 1

P (phosphorus), N (nitrogen), Bi (Bismuth)

Answer 2

Answer: The elements present in Group 5A are Nitrogen (N), Phosphorus (P) and Bismuth (Bi).

Step-by-step explanation:

The elements belonging to Group 5A has an electronic configuration
`ns^2np^3` where n is the number of periods.

For the given options, the electronic configuration of the elements are:

1. Se =
`[Ar]4s^23d^(10)4p^4`

2. Te =
`[Kr]5s^24d^(10)5p^4`

3. Po =
`[Xe]6s^24f^(14)5d^(10)6p^4`

4. Rb =
`[Kr]5s^1`

5. Xe =
`[Kr]5s^24d^(10)5p^6`

6. Sn =
`[Kr]5s^24d^(10)5p^2`

7. Pb =
`[Xe]4f^(14)5d^(10)6s^26p^2`

8. N =
`1s^22s^22p^3`

9. P =
`1s^22s^22p^63s^23p^3`

10. Bi =
`[Xe]4f^(14)5d^(10)6s^26p^3`

From the above configurations, the elements belonging to Group 5A are Nitrogen (N), Phosphorus (P) and Bismuth (Bi).
