(redirected from Atomic weights)Also found in: Thesaurus, Medical, Encyclopedia. Related to Atomic weights: nuclear atomatomic weight n. The average mass of an atom of an element, usually expressed relative to the mass of carbon 12, which is assigned 12 atomic mass units. American Heritage®...
The term "atomic weight" consists of the word "atom" which allows one to infer that the term is related to atoms. Atoms are molecules that consists of subatomic particles: electrons, neutrons and protons:Answer and Explanation: Atomic weight- also known as atomic mass- refers to the ...
The standard atomic weightsAtomWeight
As I pointed out,the conditions of the experiment precluded any accuracy of measurement sufficient to decide whether the chemical atomic weight then and since accepted, 132.81, did or did not represent the weight of the atom. Quite recently, K. T. Bainbridge,using Dempster's method of analysis...
