Definition that contains hydrogen atom
- acidic being or containing an acid; of a solution having an excess of hydrogen atoms (having a pH of less than 7)
- amine a compound derived from ammonia by replacing hydrogen atoms by univalent hydrocarbon radicals
- bicarbonate a salt of carbonic acid (containing the anion HCO3) in which one hydrogen atom has been replaced; an acid carbonate
- ethyl the univalent hydrocarbon radical C2H5 derived from ethane by the removal of one hydrogen atom
- valence (chemistry) a property of atoms or radicals; their combining power given in terms of the number of hydrogen atoms (or the equivalent)
- halon a compound in which the hydrogen atoms of a hydrocarbon have been replaced by bromine and other halogen atoms; very stable; used in fire extinguishers although it is thought to release bromine that depletes the ozone layer
- valency (chemistry) a property of atoms or radicals; their combining power given in terms of the number of hydrogen atoms (or the equivalent)
- hydrogenation a chemical process that adds hydrogen atoms to an unsaturated oil
- tritium a radioactive isotope of hydrogen; atoms of tritium have three times the mass of ordinary hydrogen atoms
- fluorocarbon a halocarbon in which some hydrogen atoms have been replaced by fluorine; used in refrigerators and aerosols
