(dawl-ton) The atomic mass unit; a measure of mass for atoms and subatomic particles.

in reference to a system of school education designed by Helen Parkhurst, 1920, from Dalton, Massachusetts, U.S., where it was first adopted. For Daltonism see color blindness.

A unit of molecular mass approximately equal to that of a hydrogen atom or 1.66 x 10-24 grams. Alternatively, there is approximately 1 mole of daltons per gram.

A dalton is a unit of mass equal to 1/12 the mass of a carbon-12 atom. The abbreviation for dalton is amu or u. 1 amu = 1.66053873x10-27 kgAlso Known As: atomic mass unit, amu

A unit of mass equivalent to the mass of a hydrogen atom (1.66 x 10-24

One twelfth of the mass of an atom of the isotope carbon-12, equal to 1.66033 × 10–27kg. Also known as the atomic mass unit or the unified mass unit. The mass of a molecule in daltons is close to the number of protons plus neutrons contained in its constituent atoms.

(n) English chemist and physicist who formulated atomic theory and the law of partial pressures; gave the first description of red-green color blindness (1766-1844)

Unit of molecular mass approximately equal to the mass of a hydrogen atom (1.66 × 10−24 g).

Atomic mass is not measured in pounds or grams. Scientists used something called Daltons. One Dalton is equal to one-twelfth the mass of a carbon atom. Scientists also call a Dalton an Atomic Mass Uni [..]

A unit of mass designated as one-sixteenth the mass of oxygen-16, the lightest and most abundant isotope of oxygen. The dalton is equivalent to one mass unit.

British fiscal economist and prominent Labour politician, Hugh Dalton was a student of A.C. Pigou and J.M. Keynes. His main professional interest was ...

measure of molecular weight or mass. One hydrogen atom has mass of 1 Da. Proteins and other macromolecule molecular weights are usually measured in kDa or kD (kilodaltons) - 1000 Da.

From an English surname that was originally derived from a place name meaning "valley town" in Old English. A notable bearer of the surname was John Dalton (1766-1844), the English c [..]
