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...

The most expensive metal in the world
Do you think the most expensive metal is gold? No! On earth there are more valuable metals. But we need to divide the value of metals that occur in nature, and metals - isotopes, which are obtained in special laboratories. Let’s look at natural metals first.

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...

Eluant or eluent
The solvent used in the process of elution, as in liquid chromatography.
Electrodes
Surfaces upon which oxidation and reduction half-reactions, occur in electrochemical cells.
Substitution Reaction
A reaction in which an atom or a group of atoms is replaced by another atom or group of atoms.
Diagonal Similarities
Refers to chemical similarities in the Periodic Table of elements of Period 2 to elements of Period 3 one group to the right, especially evident toward the left of the periodic table.
Molecular Orbital
An orbit resulting from overlap and mixing of atomic orbitals on different atoms. An MO belongs to the molecule as a whole.
Hydrogen Bond
A fairly strong dipole-dipole interaction (but still considerably weaker than the covalent or ionic bonds) between molecules containing hydrogen directly bonded to a small, highly electronegative atom, such as N, O, or F.
Polydentate
Refers to ligands with more than one donor atom.
Boyle's Law
At constant temperature the volume occupied by a definite mass of a gas is inversely proportional to the applied pressure.
Ion Product for Water
Equilibrium constant for the ionization of water, Kw = [H3O+][OH-] =1.00 x 10-14 at 25 °C.
Effective Collisons
Collision between molecules resulting in a reaction, one in which the molecules collide with proper relative orientations and sufficient energy to react.
