The Atom has cloud and nucleus, cloud has electrons, nucleus has protons and neutrons. It shows on the Periodic table, when each Element, they have the atomic number, it is protons, and using the formula to find neutrons. Everytime the atom is neutral, electrons and protons are equal. The Bohr Model shows about how atom’s energy change when atom absorbs. And the hydrogen is only have one electron. The electrons in an atom cannot exist between energy levels. The Bohr Model provided results with experiments using hydrogen atom. But it needs more electrons to have a good result of doing it.
