The Atomic Number of Nitrogen is 7
The valency of Nitrogen is 3
The Electronic Configuration of Nitrogen is
K shell --> 2
L Shell --> 5
So the valence electron present in Nitrogen is 5.

Valence Electrons in Nitrogen Atom

Nitrogen is a chemical element with the symbol N and atomic number 7. It is a nonmetal that belongs to the group 15 elements of the periodic table. The number of valence electrons present in a nitrogen atom can be determined by understanding its electronic configuration.

Electronic Configuration of Nitrogen

The electronic configuration of nitrogen is 1s² 2s² 2p³. This means that nitrogen has a total of 7 electrons distributed in different energy levels and orbitals. The first energy level (K) has 2 electrons, while the second energy level (L) has 5 electrons. The L energy level contains two sub-levels, s and p, with the s sub-level having 2 electrons and the p sub-level having 3 electrons.

Valence Electrons in Nitrogen

Valence electrons are the outermost electrons of an atom that participate in chemical reactions. In the case of nitrogen, the valence electrons are the electrons in the p sub-level of the second energy level. Therefore, the number of valence electrons in a nitrogen atom is 3.

Conclusion

In conclusion, nitrogen has a total of 7 electrons and 3 valence electrons. Understanding the electronic configuration of an element helps to determine the number of valence electrons it possesses. Valence electrons play a crucial role in chemical bonding and reactions, making them an important aspect of chemistry.
