The general electronic configuration of nitrogen is 2, 5. In this article, we will study the number of electrons an atom of nitrogen has and its electronic configuration.
Nitrogen
Nitrogen is a chemical element and has the chemical symbol N and atomic number 7. It is a nonmetal with a diatomic molecule N2, which makes up about 78% of Earth's atmosphere. Nitrogen is essential to life, as it is a component of many biomolecules, such as amino acids, DNA, and RNA. It is also used in the production of fertilizers and explosives, and in many industrial and laboratory processes. Nitrogen is a relatively unreactive element, but it can form compounds with other elements through processes such as nitrogen fixation, which converts atmospheric nitrogen into biologically usable forms.
1. Electron Configuration of Nitrogen
The electron configuration of nitrogen is: 1s2 2s2 2p3 [caption id="attachment_649" align="aligncenter" width="1280"]

The electrons in the 2p subshell are paired up in two of the three available p orbitals, and the remaining p orbital has one unpaired electron. This unpaired electron is what makes nitrogen a reactive element, as it can participate in chemical reactions to form bonds with other atoms or molecules.
2. Valence Electrons in Nitrogen
There are seven electrons in a nitrogen atom. They are arranged in the electron configuration 1s2 2s2 2px1 2py1 2pz1Â in the ground state. It thus has five valence electrons in the 2s and 2p orbitals, three of which are unpaired (the p-electrons).
3. Occurrence of Nitrogen
Nitrogen is the most abundant gas in Earth's atmosphere, making up about 78% of the air we breathe. It also occurs in various forms in the environment and in living organisms. Some common occurrences of nitrogen are:
Atmosphere: As mentioned, nitrogen is the primary gas in Earth's atmosphere, making up approximately 78% of the air we breathe.
Nitrogen fixation: Nitrogen fixation is the process by which atmospheric nitrogen is converted into a biologically usable form by certain types of bacteria and cyanobacteria. This process occurs naturally in soil, water, and in the roots of leguminous plants.
Fertilizers: Nitrogen is an important component of fertilizers, which are used to enhance plant growth and crop yields.
Biological systems: Nitrogen is a key component of many biomolecules, such as proteins, nucleic acids, and amino acids. It is also a key element in the process of photosynthesis in plants.
Industrial processes: Nitrogen is used in a variety of industrial processes, including the production of ammonia, which is used in fertilizers and other chemical processes. It is also used in the production of nitric acid, which is used in the production of explosives, dyes, and other chemicals.
Key Takeaways
The chemical symbol of nitrogen is N.

FAQs
1. What is the electronic configuration of nitrogen?
The electronic configuration of nitrogen is 1s2 2s2 2p3. This means that a nitrogen atom has two electrons in its 1s subshell, two electrons in its 2s subshell, and three electrons in its 2p subshell.
2. Why is nitrogen's electronic configuration important?
The electronic configuration of an element determines its chemical and physical properties, including its reactivity and ability to form bonds with other elements. In the case of nitrogen, its electronic configuration of three valence electrons in the 2p subshell gives it a strong tendency to form covalent bonds with other atoms.
3. How many valence electrons does nitrogen have?
Nitrogen has three valence electrons, which are located in the 2p subshell. These electrons are unpaired and can participate in chemical bonding with other atoms or molecules.
4. What is the significance of the unpaired electron in nitrogen's electronic configuration?
The unpaired electron in the 2p subshell of nitrogen gives it a high reactivity and makes it capable of forming strong covalent bonds with other atoms. This reactivity is what makes nitrogen a key component of many biological molecules and industrial processes.
5. How does the electronic configuration of nitrogen relate to its chemical properties?
The electronic configuration of nitrogen gives it a strong tendency to form covalent bonds, which is why it is a key component of many biological molecules and industrial processes. Nitrogen also has a high electronegativity due to its electronic configuration, which contributes to its ability to form strong bonds with other elements.
