typpiatomeja

Typpiatomeja, also known as nitrogen atoms, are fundamental building blocks of matter. Nitrogen is the seventh element on the periodic table with the symbol N. A single nitrogen atom has a nucleus containing seven protons and, in its most common isotope, seven neutrons. Surrounding this nucleus are seven electrons. These electrons are arranged in specific energy shells, with two electrons in the inner shell and five in the outer valence shell. This configuration of five valence electrons makes nitrogen highly reactive, readily forming chemical bonds with other atoms.

Nitrogen atoms are essential for life. They are a key component of amino acids, the building blocks of proteins, and nucleic acids, which carry genetic information (DNA and RNA). In the Earth's atmosphere, nitrogen exists primarily as diatomic nitrogen gas (N2), where two nitrogen atoms are joined by a triple covalent bond. This bond is very strong, making atmospheric nitrogen relatively inert. However, biological processes and industrial applications convert this nitrogen into more reactive forms that can be utilized by living organisms or incorporated into various compounds. The cycle of nitrogen through the environment is crucial for sustaining ecosystems.
