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.
What the maximum number of electron can go in the first three energy levels subatomic particles? Level 1 - 2 electrons Level 2 - 8 electrons Level 3 - 18 electrons Level 4 - 32 electrons Level 5 - 50 electrons
