Energy Levels in the Periodic Table Sciencing

WebThere are 2 in the first energy level, 6 in the second, and 2 in the third. There are a total of 10 electrons. To be in the ground state, the 10 electrons must first fill the innermost shell, which can hold 2. So we have 8 electrons left. WebSo the total energy is E = K +U = 1 2 U = − 1 2 ke2 r (9) The fact that the total energy is negative means that the electron is bound to the proton. So as the electron gets farther and farther away, the energy approaches 0. In general, −∞ < E < 0. To get quantized energy levels, Bohr proposed that the electron’s orbital angular momentum ... flyzone rc beaver
