Question

How would electrons produced in a cathode ray tube filled with neon gas compare with the electrons produced in a cathode ray tube filled with chlorine gas?

Answer 1

The biggest difference would be due to the fact that neon gas consists of atoms while chlorine gas is a molecule (Cl2). A neon spectra will consist of a series of distinct lines. The chlorine spectra will consist of bands. (You probably would also see some lines too, because some of the Cl2 will become dissociated into chlorine atoms.)
