An atom in an excited state will on the average undergo a transition to a state of lower energy in about 10 8 seconds If the electron in a doubly ionized lithium atom (Li 2 , which is hydrogenlike) is placed in the n 4 state, about how many revolutions around the nucleus does it make before undergoing a transition to a lower energy state

Question: An atom in an excited state will on the average undergo a transition to a state of lower energy in about 10 -8 seconds. If

An atom in an excited state will on the average undergo a transition to a state of lower energy in about 10^-8 seconds. If the electron in a doubly ionized lithium atom (Li⁺², which is hydrogenlike) is placed in the n = 4 state, about how many revolutions around the nucleus does it make before undergoing a transition to a lower energy state?
