The mass number of an atom is the total number of protons and neutrons contained within the nucleus of the atom. The number of protons determines the element and will always equal the atomic number of that element. The number of neutrons can change and will determine which isotope of that...
combining weight,eq,equivalent weight,equivalent- the atomic weight of an element that has the same combining capacity as a given weight of another element; the standard is 8 for oxygen meq,milliequivalent- one-thousandth of an equivalent
aGiven the atom and mass ratios of X to oxygen, you need to figure out the mass of X that combines with 47.998 u O, i.e., the mass of three O atoms. At this point you divide by 2 and the result should appear some place in the periodic table! 假使X原子和大量比率氧气,您需要...
Conservation of mass, principle that the mass of an object or collection of objects never changes, no matter how the constituent parts rearrange themselves. Mass has been viewed in physics in two compatible ways. On the one hand, it is seen as a measure
THE weak doublets of the atmospheric absorption bands of oxygen have been found to originate from a molecule consisting of an oxygen atom of mass 18 combined with one of mass 16. The interpretation recently published by Mulliken (Phys. Rev., 32, 880; 1928) for the strong bands holds in ...
1/12 the mass of a neutral atom of 12C, equal to 931.5 MeV. Atomic number (Z) Integer equal to the number of protons in a nucleus; the order of an element in the periodic table. Atomic weight or nuclear mass number (A) An integer equal to the sum of the number of protons Z and...

The elements defined the atomic mass unit as '1/16th of the atomic weight of oxygen'. Apart from the fact that the term mass should have been used instead of weight, this definition does not specify which oxygen isotope, and implies the average mass of an oxygen atom in the mixture of ...
Atomic mass unit is one-twelfth the mass of an atom of carbon-12 (12C), the most common carbon isotope. Nonetheless, the termapproximatematters because the masses of individual atoms in elements -- other than carbon -- are not whole numbers (see above examples). This is because mass is ...
