An atom of hydrogen undergoes a collision with another atom in a hot gas, the energy of collision being about 11 eV. What is the probable outcome of this collision in terms of the atom? A)An electron is excited to the first excited level, n = 2. Its return to the ground state produces a L_α UV photon. B)An electron is excited to the first excited level, and de-excitation to the ground state produces a visible photon of Balmer H_α light. C)An electron is excited to the second excited level, n = 3, and de-excitation generates either a L_ß UV Lyman photon or an H_α visible and a L_α UV photon. D)An electron is excited beyond the ionization level, the atom will be ionized and the electron leaves the atom completely.
