Question

what is the frequency of light released when electron moves from the second energy level to the first energy level in hydrogen?​

Answer 1

Answer:5 -2.176 eV

Step-by-step explanation:

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.
