- 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...

Acid
A substance that produces H+(aq) ions in aqueous solution. Strong acids ionize completely or almost completely in dilute aqueous solution. Weak acids ionize only slightly. Chemicals or substances having the property of an acid are said to be acidic.
Effective Molality
The sum of the molalities of all solute particles in a solution.
Atomic Weight
Weighted average of the masses of the constituent isotopes of an element, The relative masses of atoms of different elements.
Dispersing Medium
The solvent-like phase in a colloid.
Insoluble Compound
A very slightly soluble compound.
Actual Yield
Amount of a specified pure product actually obtained from a given reaction. Compare with Theoretical Yield.
Nonpolar Bond
Covalent bond in which electron density is symmetrically distributed.
Combustible
Classification of liquid substances that will burn on the basis of flash points. A combustible liquid means any liquid having a flash point at or above 37.8°C (100°F) but below 93.3°C (200°F), except any mixture having components with flash points of 93.3°C (200°F) or higher, the total of which makes up 99 percent or more of the total volume of the mixture.
Conjugate Acid-base Pair
In Bronsted-Lowry terminology, a reactant and product that differ by a proton, H+.
Bonding Orbital
A molecular orbit lower in energy than any of the atomic orbitals from which it is derived, lends stability to a molecule or ion when populated with electron.
