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.
Best Answer: When electrons in an atom get excited, they jump to higher energy levels. In order for them to do this, they must absorb energy.However, when electrons calm down, they drop back down and thus release emit energy in the form of photons (the quanta of light).est Answer: When electrons in an atom get excited, they jump to higher energy levels.
