Answer:
5 Electrons.
Explanation:
Hello.
In this case, an element in group 15 such as nitrogen has 5 electrons on the outer shell because of its electron configuration. For N, whose atomic number is 7, the electron configuration is:
[tex]N^7: 1s^2,2s^2,2p^3[/tex]
Whereas energy level 2 has 5 electrons (2 from 2s and 3 from 2p). Next element is phosphorous and its electrons configuration is:
[tex]P^{15}:1s^2,2s^2,2p^6,3s^2,3p^3[/tex]
It also has 5 electron on the energy level 3 (2 from 3d and 3 from 3p).
Best regards!
