A deuterium nucleus; namely, a proton and a neutron. It is used in nuclear applications, such as the bombardment of molybdenum plates to create technetium plates. With an electron, it forms the stable hydrogen isotope of deuterium or "heavy hydrogen", symbol D, atomic wt. 2. Water with both hydrogens replaced by deuterium is called "heavy water" (D2O), and is used as a moderator in the harnessing of nuclear fuels.
I swear that deuterons have somethingy to do with the book of Deuteronomy, 5th book of the Old Testament.

one of at least two different forms of an element. Different allotropes of a substance often have very different properties from each other; e.g. white phosphorus (P4) is a highly reactive and toxic substance that glows in air due to its high reactivity and possesses a molecular structure, while red phosphorus (the stuff used to make strikers on match boxes) is a non-toxic substance that has a polymeric structure.
White tin is a shiny, electrically conductive metal usefull for plating cans to prevent corrosion, while gray tin is a semiconductor that possesses no uses whatsoever

The light of the noble gasses, at. no. 2, used as a lifting agent for zeppelins and balloons. If you inhale it, your voice will sound really funny like you're pinching your nose. Just don't asphyxiate yourself, or you'll be sorry.

the fourth most spoken language on Earth (after body, Chinese, and what's-it-called). Because of its high saturation of words and numerous associations to the number 43, atomic number of technetium, it is considered to be a radioactive language, which decays by alpha-particle emission to Latin.

The first element on the periodic table. Burns with glee when lit, and explodes when lit near oxygen.
