Electrons in a hydrogen atom must be in one of the allowed energy levels. If an electron is in the first energy level, it must have exactly -13.6 eV of energy. If it is in the second energy level, it must have -3.4 eV of energy. An electron in a hydrogen atom cannot have -9 eV, -8 eV or any other value in between. Let's say the electron wants to jump from the first energy level, n = 1, to the second energy level n = 2. The second energy level has higher energy than the first, so to move from n = 1 to n = 2, the electron needs to gain energy.
1 electrons in the third orbit belong to the third energy level 2  ...... etc 3  ...... each energy level of an atom could only accomodate a certain number of electrons. 4  The maximum number of electrons that can populate a certain energy level is given by the following formula. The maximum number of electron in the first energy level (n = 1) is 2 (1) 2 = 2 electrons. 2  The maximum number of electron in the second energy level (n = 2) is 2 (2) 2 = 8 electrons. 3  The maximum number of electron in the third energy level (n = 3) is 2 (3) 2 = 18 electrons 4  .... etc ...
