technetium

A silvery element, at. no. 43, symbol Tc, that does not appear to occur in the Earth's crust at all due to its radioactivity. It is the lightest radioactive element and is produced by deuteron bombardment of molybdenum.
Technetium is one of the most powerfull preventatives of rust.

A noted Haddonfield composer who has written many works, such as Ode to Dallas. He is a big fan of the Cowboys, and as such his works have not quite achieved fame yet. His pastimes include watching football, playing the trumpet, and competing on the Academic Challenge team with Cashcow and Ezkett. He is a man of few words, but his saying hold immense wisdom.
Wolfgang: Hey mips-hater do you have the english homework?
Cashcow: How are you Wolfgang!
Wolfgang: That's me.

helium

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.
When he let go of his balloon, it floated up into the air because of the helium inside it.

hydrogen

The first element on the periodic table. Burns with glee when lit, and explodes when lit near oxygen.
That stupid guy lit some hydrogen he mixed with some oxygen.

Spanish

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.
Our map was in Spanish a few minutes ago. Now it's all in Latin, and it glows too.

allotrope

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
