Consider aiming a beam of free electrons towards free protons. When they scatter, an electron and a proton cannot combine to produce an H-atom,
(a) because of energy conservation
(b) without simultaneously releasing energy in the form of radiation
(c) because of momentum conservation
(d) because of angular momentum conservation
