Neon is an element belonging to the noble gas group, located in group 18 of the periodic table with an atomic number of 10. Its atomic mass is approximately 20.18 g/mol. Under standard conditions it exists as a colorless odorless and tasteless gas. Although present in the atmosphere in very low concentrations (approximately 0.0018% by volume) its distinctive spectral properties and chemical inertness make it useful in various scientific and technological applications.DiscoveryNeon was discovered

Throughout history, humans have examined the materials around them and attempted to classify them. Although in ancient times substances such as water, air, earth, and fire were considered “classical elements,” the discovery of true elements began only after the 1600s. An element is a pure substance that cannot be broken down into smaller components.Organizing the ElementsIn the 1700s and 1800s many new elements were discovered. However, arranging these elements in a meaningful way proved difficu

Nitrogen, also known as dinitrogen, is a nonmetallic element in Group 15 of the periodic table, with an atomic number of 7. Its atomic mass is approximately 14.00674 g/mol. Under standard conditions, nitrogen exists as a diatomic gas (N₂) that is colorless, odorless, and tasteless. It constitutes about 78% of the Earth’s atmosphere by volume. Nitrogen is an essential component of fundamental biomolecules such as DNA, RNA, and proteins, playing a critical role in the structure and function of liv
