The atomic mass of the element is determined by the combined masses of neutrons and protons. True or false? Explain. Answer and Explanation: The atomic mass or atomic weight of an element (or put it in simple term, mass of an atom) is found ...
1 The relative atomic mass of an element is always D A the mass of an atom of the element relative to z the mass of a carbon-12 atom. B the mass of an atom of the element relative to the mass of a hydrogen atom.□ C the weighted mean mass of an atom of the element relative...

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 ...
(40.1) is the potential energy of an atom. Therefore we can also state this particular law as: the density at any point is proportional to e^{−\text{the potential energy of each atom}/kT}. That may be an accident, i.e., may be true only for this particular case of a uniform ...
