Multiple Choice
An atom of hydrogen undergoes a collision with another atom in a hot gas in which the energy of collision is about 11 eV.What is the likely outcome of this collision in terms of the atom? (See Figure 3-51,Comins,Discovering the Essential Universe,6th ed.)
A) The electron in the atom will be excited to the second excited level, n = 3, and de-excitation will generate either an Lα UV Lyman photon or an Hα visible and an Lα UV photon.
B) The electron in the atom will be excited to the first excited level, n = 2. Its return to the ground state will produce an Lα UV Lyman photon.
C) The electron in the atom will be excited to the first excited level, and de-excitation to the ground state will produce a visible photon of Balmer Hα light.
D) The electron of the hydrogen atom will be excited beyond the ionization level (n = ∞) ; the atom will be ionized, and the electron will leave the atom completely.
