We can draw two conclusions. First, the electron in a hydrogen atom can exist only with certain energies, corresponding to motion in what we now call a state or an orbital. Second, the energy of a state can be characterized by an integer quantum number, n = 1, 2, 3,... which determines its energy.

Each … WebJun 2, 2024 · No matter how many electrons or neutrons an atom has, the element is defined by its number of protons. In fact, it's actually possible to have an atom consisting of only a proton (ionized hydrogen). The periodic table is arranged in order of increasing atomic number, so the number of protons is the element number. For hydrogen, the number of ... high speed internet aurora co
