Nitrogen(N) is the 7th aspect in the periodic table and also the very first element in group-15. The typical atomic massive of nitrogen is 14.006 and also its symbol is ‘N’. Nitrogen participates in the development of bonds through valence electrons. This write-up discusses in detail the valence electron of nitrogen. Hopefully, after analysis this post you will recognize in detail about this.

You are watching: Number of valence electrons for nitrogen


How numerous electrons, protons and also neutrons walk a nitrogen(N) atom have?

The cell core is situated in the facility of the atom. Protons and neutrons are located in the nucleus. The atomic variety of nitrogen is 7. The atomic number is the number of protons. The is, the variety of protons in the nitrogen is seven. Electrons equal to proton are situated in a one shell external the nucleus. That is, nitrogen atoms have a complete of seven electrons.

The variety of neutrons in an element is obtained from the difference in between the variety of atomic masses and also the number of atoms. That is, neutron number (n) = atom mass number (A) – atom number (Z)

We know that the atomic number of nitrogen is 7 and the atom mass number is 14. Neutron (n) = 14 – 7 = 7. Therefore, the variety of neutrons in nitrogen(N) is 7.

What room the valence electron of nitrogen(N)?

The total number of electrons in the last covering after the electron construction of nitrogen is dubbed the valence electrons of nitrogen. The valence electron is the total number of electrons in the last orbit. The valence electron determine the properties of the element and also participate in the formation of bonds.

Valency the nitrogen

Again, Valence is determined from the electron configuration of the facet in the excited state. The electron construction of nitrogen in excited state is N*(7) = 1s2 2s2 2px1 2py1 2pz1. Here, the electron construction of nitrogen reflects that three unpaired electron exist. In this case, the valency the the nitrogen atom is 3.

How many valence electrons does nitrogen ion(N3-) have?

After arranging the electrons, that is watched that the last covering of the nitrogen atom has 5 electrons. In this case, the valence electrons of nitrogen are 5. We know the details about this.

The aspects that have 5, 6, or 7 electron in the last shell(orbit) receive the electrons in the critical shell during bond formation. The elements that get electrons and type bonds are called anions. The is, nitrogen is an anion element.

N + 3e–→ N3-

During the development of nitrogen bonds, the last covering receives electrons and also turns them into nitrogen ions. The electron configuration of nitrogen ions(N3-) is 1s2 2s2 2p6. The electron construction of nitrogen ion(N3-) reflects that nitrogen ions have two shells and also the second shell has eight electrons. The electron configuration shows that the nitrogen ion has obtained the electron configuration of neon.

That is, in this case, the valence the nitrogen ions is -3. Because the last covering of a nitrogen ion has actually eight electrons, the valence electron of nitrogen ion(N3-) space eight.

Compound development of nitrogen by valence electrons

Nitrogen participates in the development of bonds with its valence electrons. This valence electron participates in the formation of bonds v atoms of various other elements. Nitrogen atoms kind bonds by share electrons v hydrogen atoms. The electron configuration of hydrogen mirrors that hydrogen has only one electron. 3 hydrogen atoms and one nitrogen atom do ammonia(NH3) compounds by sharing electrons.

As a result, the nitrogen atom completes that is octave and acquires the electron construction of neon. On the various other hand, hydrogen acquires the electron configuration of helium. Therefore, one nitrogen atom share electrons with three hydrogen atoms to type the ammonia(NH3) compound v covalent bonding.
