WebExplain what determines the mass and charge of individual atoms. The mass of an atom is the total of the mass of the protons and neutrons. The charge of an atom is the number of protons and electrons an atom has. Describe nuclear notation (referred to as isotope notation in the video). WebVideo transcript. - In the Bohr model of the hydrogen atom we have one proton in the nucleus. So I draw in a positive charge here and a negatively charged electron orbiting the nucleus, so kind of like the planets orbiting the sun. Even though the Bohr model is not reality it is useful for a concept of the atom. notyourgothgirlfriend
