A hydrogen atom collides with a particle that delivers 8.32 eV of energy to the atom. The electron in the atom absorbs this energy and escapes the nucleus. The electron is later detected when it is far from the nucleus. And it's kinetic energy is 6.80eV. What wuantum state (value of n) was the electron in just before collision?
