Since a hydrogen atom consists of just one proton and one electron, it should have a mass of 1.673 times 10^{-24} g. And so it does. Calculate how many hydrogen atoms you'd have if you had 5.6 g of hy An atom is selected at random from a sample ...
Atoms are proved to be semi-classical electronic systems in the sense of closeness of their exact quantum electron energy spectrum with that calculated within semi-classical approximation. Introduced semi-classical model of atom represents the wave funct
the researchers instead attempted to measure the attraction between a cloud of cold rubidium atoms and tungsten weights. They came up with a value for G of 6.67191(99) x 10−11
