A Hydrogen atom has one proton in the nucleus and one electron in the shell. In a classic model of the atom, in a certain state, this electron is in a circular orbit around the nucleus with an velocity of 545364.928909953 m/s.
What is the radius of the orbit?
What is the angular momentum, L, of the electron at this radius?
What is the quantum value, n, of the electron at this radius?
