Gas Gang Chloroform, Carbon Monoxide, and Carbon Dioxide. Whereas the Metal Men were approximately the same size as Doctor Magnus, the Gas Gang were anywhere from one-third to twice his size. On Chloroform's initial attack, it caused the Metal Men to break out in fits of hysteria ala Nitrous Oxide (Laughing Gas) which Doc Magnus said was chloroform's initial effect. Before Lead could wall them off, Mercury literally "broke up laughing", opening Oxygen to attack and causing the Metal Men to begin to rust. During the chase Carbon Monoxide (called "CM" by Carbon Dioxide) attempted to poison them with fumes, while Carbon
Abundance of the chemical elements Abundance of the chemical elements The abundance of the chemical elements is a measure of the occurrence of the chemical elements relative to all other elements in a given environment. Abundance is measured in one of three ways: by the mass-fraction (the same as weight fraction); by the mole-fraction (fraction of atoms by numerical count, or sometimes fraction of molecules in gases); or by the volume-fraction. Volume-fraction is a common abundance measure in mixed gases such as planetary atmospheres, and is similar in value to molecular mole-fraction for gas mixtures at relatively low densities and pressures, and ideal gas mixtures.
