Atomic mass unit (amu) is one twelfth of carbon-12 atom's rest mass. One dalton equals approximately one proton or neutron mass. Value is 1.660538921(73)×10−27 kg
Quarks and leptons are the smallest fundamental particles in the universe. Atoms consist of protons, neutrons, and electrons. Neutrons and protons are made of multiple quarks
Atom is an open-source text editor developed by GitHub. It combines web technologies with Python integration. Supports multiple programming languages including Python. Features built-in package manager and extensive plugin library
Ununennium (Uue) is element 119, the smallest undiscovered element. Elements near N=184 and N=196 cannot form naturally. All neutron-rich Uue isotopes will disappear within 1000 seconds
Standard atomic weight (Ar°) is weighted mean of isotopic masses on Earth. Values are determined by CIAAW based on natural, stable terrestrial sources. Atomic weights are dimensionless quantities, converted to mass with dalton
