WebThe Bohr model of the hydrogen atom explains the connection between the quantization of photons and the quantized emission from atoms. Bohr described the hydrogen atom in terms of an electron moving in a circular orbit about a nucleus. He postulated that the electron was restricted to certain orbits characterized by discrete energies. WebIt's all in the definition. The energy is defined as zero when the electron is an infinite distance from the nucleus. As the electron comes closer, the energy decreases, so the energy of the system becomes negative. Even for an H atom in an excited state, the energy is negative, but it is less negative than for an atom in the ground state. creekstone farms logo https://pineleric.com
