How does a Geiger counter measure radiation levels? Radiation is absorbed by gas atoms, which undergo phosphorescence and emit a different radiation.
Radiation is absorbed by gas atoms, which undergo nuclear reactions and emit a different radiation.
Radiation knocks neutrons out of gas atoms, which causes the gas atoms to become unstable.
Radiation knocks electrons out of gas atoms, which allows the gas to conduct an electric current.

The two naturally occurring isotopes of chlorine are 35cl (34.969 amu, 75.77%) and 37cl (36.966 amu, 24.23%). the two naturally occurring isotopes of bromine are 79br (78.918 rm amu, 50.69%) and 81br (80.916 amu, 49.31%). chlorine and bromine combine to form bromine monochloride, brcl. 1. how many peaks will be present in a mass spectrum for brcl? the four combinations of molecule possible given these four isotopes are: 81br37cl, 81br35cl, 79br37cl, and 79br35cl. 2. what are the masses of the four different brcl molecules? express the masses using six significant figures, in decreasing numeric order (highest to lowest), separated by commas.
