WebMar 11, 2024 · There you see that there are 2 electrons in the first energy level (n = 1) and 6 electrons in the second energy level (n = 2). You can know this by looking at the periodic table because the number of energy levels (shells) is equal to the period of the atom, i.e. the row in the periodic table. Oxygen is the the second row of the periodic table ... WebWith this convention, the different energy levels of a Hydrogen atom are given by the equation: where E0 = 13.6 eV ( 1 eV = 1.602×10-19 Joules) and n = 1,2,3… and so on so that the ground state has energy E1= -13.6 eV and the second energy level (the first excited state) has energy E2 = -13.6/4 eV = -3.4 eV. green punch for st patrick\u0027s day
