Hydrogen (1 H) has three naturally occurring isotopes, sometimes denoted 1 H, 2 H, and 3 H. 1 H and 2 H are stable, while 3 H has a half-life of 12.32(2) years. [3] [nb 1] Heavier isotopes also exist, all of which are synthetic and have a half-life of less than one zeptosecond (10 −21 s).
Trichlorobenzene (TCB) may refer to any of three chlorobenzenes with the molecular formula C 6 H 3 Cl 3. [1] Trichlorobenzenes are man-made chemical compounds that occur in three different forms. Even though the forms have the same molecular weight and molecular formulae, they are structurally different by the positions of the chlorine atoms ...
