This list includes 8 Chemical Elements that start with N, from “Neodymium” to “Nobelium”. These elements range from common metals used in magnets and alloys to heavy, mostly synthetic atoms used in research. See the A–Z index.
Chemical Elements that start with N are a small group that includes both naturally occurring metals and heavy synthetic elements. Neodymium is famous for strong permanent magnets, while Nobelium honors Alfred Nobel and marks advanced nuclear research.
Below you’ll find the table with atomic number, atomic weight, and discovery year.
Atomic number: The integer that tells you how many protons an atom has and helps you identify element order in the table.
Atomic weight: The standard atomic mass with three decimals that helps you compare relative mass for calculations and reference.
Discovery year: The year or era when the element was identified or isolated, useful for historical context and study timelines.

Descriptions
Nitrogen
Discovered 1772; Natural; makes up ~78% of Earth’s atmosphere and is essential for life, forming amino acids and fertilizers.
Neon
Discovered 1898; Natural; a noble gas rare in air, famous for its bright red-orange glow in neon signs and discharge tubes.
Nickel
Discovered 1751; Natural; a hard, silvery metal used in stainless steel, coins and batteries; ferromagnetic at room temperature.
Niobium
Discovered 1801 (clarified 1846); Natural; a corrosion-resistant metal used in steel alloys and superconducting magnets, once called columbium.
Neodymium
Discovered 1885; Natural; a rare-earth metal used in very strong permanent magnets for motors, headphones and wind turbines.
Neptunium
Discovered 1940; Synthetic; the first transuranic element, produced in reactors and important in nuclear research though it has no stable isotopes.
Nobelium
Discovered 1950s; Synthetic; named for Alfred Nobel, produced in particle accelerators and known only in short-lived radioactive isotopes.
Nihonium
Discovered 2003–2004 (named 2016); Synthetic; named after “Nihon” (Japan), it is very short-lived and created in fusion experiments.
