A mixture of 2 moles of helium gas (atomic mass = 4 amu) and 1 mole of argon gas (atomic mass = 4 0 amu) is kept at 3 0 0 K in a container. However, this did not explain similarities between different atoms, as expressed by the periodic table, such as why Helium (2 electrons), Neon (8 electrons), and Argon (18 electrons) exhibits similar chemical behaviour. Rutherford’s model introduced the nuclear model of an atom, in which he explained that a nucleus (positively charged) is surrounded by negatively charged electrons. Discover (and save!) In the Bohr model, electrons with less energy occupy orbits closer to the nucleus and are uninvolved in chemical … Bohr used the term energy levels (or shells) to describe these orbits of differing energy.
