Atomic Mass Number – Does it conserve in a nuclear reaction? Substances in which electricity can flow are called conductors. To understand the difference between metals, semiconductors and electrical insulators, we have to define the following terms from solid-state physics: A possible crystal structure of Chlorine is orthorhombic structure. So, 3 moles of CO2 contains (3 x 2 x 6.02 x 10*23) O atoms = 3.61 x 10*24 O atoms. Answers. total moles of chlorine atoms = number of atoms in one mole × number of formula units= 2×2= 4. Discoverer: Scientists at Dubna, Russia (1964)/Albert Ghiorso et. = 2.078x10^24. B. both chlorine atoms transfer an electron to the other chlorine atom.
