What is the percentage of nitrogen in air?

The percentage of nitrogen in the air is 78.1%.

Extra information: The Earth's atmosphere is made up of a mixture of gases called "air." These are colourless and odourless gases. It is made up of 78 % nitrogen, 21% oxygen, and 1 % other gases and water vapour. It also contains trace amounts of carbon dioxide, neon, helium, methane, krypton, hydrogen, nitrous oxide, xenon, ozone, iodine, carbon monoxide, water vapours, and ammonia.

Nitrogen: Nitrogen makes up 78% of the air in the atmosphere. The nitrogen cycle recycles nitrogen for plants, animals, and the environment. Nitrogen (N) is one of the building blocks of life: it is essential for all plants and animals to survive. When nitrogen oxides interact with water droplets in the air, they form nitric acid, causing acid rain.

Plants need nitrogen for the production of proteins, nucleic acids (DNA and RNA), and chlorophyll. Different plant parts (leaves, roots, trunks, etc.) depend on the availability of essential nutrients like nitrogen to enhance the plant's biological processes, including growth, absorption, transportation, and excretion.
