Kväveatomerna

Kväveatomerna refers to the atoms of the chemical element nitrogen. Nitrogen is a fundamental element found throughout the universe and is essential for life on Earth. Its atomic number is 7, meaning each nitrogen atom has 7 protons in its nucleus. In its elemental form, nitrogen exists as a diatomic molecule, N2, which makes up approximately 78% of Earth's atmosphere. This N2 molecule is very stable due to a triple bond between the two nitrogen atoms, requiring significant energy to break.

Nitrogen atoms readily form compounds with other elements. In biological systems, nitrogen is a key component of amino acids, the building blocks of proteins, and nucleic acids, such as DNA and RNA. Nitrogen fixation, a process where atmospheric nitrogen is converted into usable forms like ammonia, is crucial for plant growth and is carried out by certain bacteria.

Industrially, nitrogen atoms are utilized in the production of fertilizers, explosives, and nitric acid. Its inert nature also makes it useful as a protective atmosphere in various industrial processes and for preserving food. The presence and behavior of nitrogen atoms are central to many chemical and biological cycles.
