Dalton
The dalton (Da) is a unit of mass used to express atomic and molecular weights, equivalent to one atomic mass unit (amu).
History/Origin
The dalton was named after John Dalton, who developed early atomic theory in the early 19th century. It has been widely used in chemistry and biochemistry to measure atomic and molecular masses.
Current Use
The dalton is commonly used in scientific contexts to specify the mass of atoms, molecules, and subatomic particles, facilitating precise communication in chemistry, biochemistry, and molecular biology.
Proton Mass
The proton mass (m_p) is the mass of a proton, a subatomic particle found in the nucleus of an atom, approximately 1.6726219 × 10⁻²⁷ kilograms.
History/Origin
The proton mass was first measured in the early 20th century through experiments involving atomic and nuclear physics, notably by Ernest Rutherford and subsequent researchers refining the value through scattering experiments and mass spectrometry.
Current Use
The proton mass is used as a fundamental constant in physics and chemistry, serving as a standard unit of mass in atomic and nuclear calculations, and is essential in defining atomic mass units and understanding nuclear reactions.
