which of the following is consistent with the line spectrum of the hydrogen atom?

Question

one of the choices is the nucleus is udnergoing gamma decay. but this si not one of the answers. Im just wondering what kind of decay happens?

Answer 1

What are the other choices. There is no decay going on with the H line spectrum. The H line spectrum is simply an electron in a higher energy level moving to a lower energy level. The difference in energy between the higher state and the lower state is emitted.
