Gas of rotten eggs
If you happen to break a rotten egg, then you know the smell of hydrogen sulfide, because the stench of the spoiled egg depends on of its presence in rotting protein substances.

Features of the Scanning Tunneling Microscope
The scanning tunneling microscope (STM) invented by Heinrich Rohrer and Gerd Binnig in the 1980s still manages to do a great job today and competes with more advanced microscope types. The scanning tunneling microscope is used for studying the surface atoms that are found on various materials. The...

Varieties of garnet minerals
The most famous type of garnet stone is pyrope (flaming). This is the "oldest of garnets", with a dense red color, similar to the grain of an edible garnet. Pyrope has a variety called rhodolite - a stone of dense pink or pink-purple color, which sometimes has the alexandrite effect and is used in...

Potential Energy
Energy that matter possesses by virtue of its position, condition or composition.
Hydrate
A solid compound that contains a definite percentage of bound water.
Hydrogenation
The reaction in which hydrogen adds across a double or triple bond.

An atom or a group of atoms that carries an electric charge.
Delocalization
Of electrons, refers to bonding electrons that are distributed among more than two atoms that are bonded together, occurs in species that exhibit resonance.
The formation of a set of molecular orbitals that extend over more than two atoms, important in species that valence bond theory describes in terms of resonance.
Ioniztion
The breaking up of a compound into separate ions.
Kinetic Energy

Atomic Mass Unit (amu)
One twelfth of a mass of an atom of the carbon-12 isotope, a unit used for stating atomic and formula weights, also called dalton.
Curie (Ci)
The basic unit used to describe the intensity of radioactivity in a sample of material. One curie equals 37 billion disintegrations per second or approximately the amount of radioactivty given off by 1 gram of radium.
