The relative mass of an atom based on a scale in which a specific carbon atom (carbon-12) is assigned a mass value of 12. 2, record 1, English, - atomic%20weight
Record number: 1, Textual support number: 1 CONT
Atomic weight. The nucleus of an atom is made up of neutrons and protons. The total mass of the neutrons and protons along with the electrons gives the mass of the atom. ... Because this value is so small, a new unit of weight, the atomic weight unit (awu), is often used to express the weights of atoms. It is defined as 1/12 the weight of carbon atom. Carbon therefore weighs 12 awu and is the chemists' standard of reference for atomic weights. 6, record 1, English, - atomic%20weight
Record number: 1, Textual support number: 2 CONT
Sometimes hydrogen is assigned an atomic weight of 1 and oxygen an atomic weight of 16, but carbon with a weight of 12 usually is taken as a basis. Every element is assigned an atomic weight. 7, record 1, English, - atomic%20weight

[La] masse atomique d'un élément [...] a été longtemps définie comme le rapport de la masse de l'atome de cet élément au seizième de la masse de l'atome d'oxygène; ainsi la masse atomique de l'oxygène était 16 [...]. [À l'occasion du] Congrès de l'Union internationale de chimie pure et appliquée (Montréal, 1961) [...] l'atome de carbone de nombre de masse 12 [a] été pris comme nouvelle base des masses atomiques [...] 5, record 1, French, - masse%20atomique

[La] Commission des poids atomiques [...] a recommandé d'utiliser la désignation poids atomique pour les éléments qui sont, pour la plupart d'entre eux à l'état naturel, des mélanges de nuclides et de réserver celle de masse atomique pour les nuclides isolés. 4, record 1, French, - masse%20atomique
