Atomic Mass Unit
The atomic mass unit (u) is a standard unit of mass used to express atomic and molecular weights, defined as one twelfth of the mass of a carbon-12 atom.
History/Origin
The atomic mass unit was introduced in the early 20th century to provide a convenient scale for atomic weights. It was originally based on the mass of hydrogen but was later standardized to be one twelfth of the mass of a carbon-12 atom, which was adopted as a reference in 1961 by the IUPAC.
Current Use
The atomic mass unit is widely used in chemistry and physics to express atomic and molecular masses, facilitating calculations in molecular chemistry, nuclear physics, and related fields.
Neutron Mass
The neutron mass (m_n) is the mass of a neutron, a subatomic particle found in the nucleus of an atom, approximately 1.675 × 10⁻²⁷ kilograms.
History/Origin
The neutron was discovered in 1932 by James Chadwick, leading to the understanding of its mass relative to protons and electrons. The neutron mass has been refined through experimental measurements in nuclear physics.
Current Use
The neutron mass is used in nuclear physics calculations, atomic mass units, and in the 'Weight and Mass' converter for scientific and educational purposes, as part of the 'Common Converters' category.
