Nitrogen is the non-metallic gaseous element present in the periodic table. Here, we are discussing the chemical properties of nitrogen element.
Nitrogen is a diatomic gaseous element represented as N2. It has no color, odor, or taste. It is an inert gas at room temperature. N2 gas covers about 78% of the Earth’s atmosphere. It plays a vital role in various chemical industries and is used as fertilizer, and in the production of nylon, nitric acid, etc.
In this article, we are discussing the symbol, electronegativity, atomic weight, group, ionization energy, van der Waal’s energy, and many more chemical properties of nitrogen.

Nitrogen allotropic forms
The atoms of similar elements that show different structural forms are called the allotropes of that element. Let us see the allotropic forms of nitrogen elements.
The nitrogen atom shows only one allotropic form. The allotropic form of nitrogen is di-nitrogen. It is represented as N2 and known as nitrogen gas. The di-nitrogen gas occurs in the Earth’s atmosphere.
Nitrogen chemical classification
The nitrogen element gets classified as a non-metallic element.
Nitrogen state at room temperature
The nitrogen element shows the gaseous state at room temperature.
Is nitrogen paramagnetic?
The presence of paired electrons shows the diamagnetic nature of an element. Let us see that the nitrogen element is diamagnetic or paramagnetic in nature.
Nitrogen is diamagnetic in nature and not paramagnetic. It does not contain any unpaired electrons. It has the paired electron in its outer orbit and on applying an external magnetic field it gets to repel each other and show a diamagnetic character.
Conclusion:
The nitrogen element has an N symbol and occurs as a gas in its di-atomic form as N2. It belongs to the 15th group and 2nd periods. It has atomic number 7 and electronegativity of 3.04. It is diamagnetic in nature and a p-block element.
