  • 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...

Open Sextet

Refers to species that have only six electrons in the highest energy level of the central element (many Lewis acids).

Weak Electrolyte

A substance that conducts electricity poorly in a dilute aqueous solution.

Cell Potential

Potential difference, Ecell, between oxidation and reduction half-cells under nonstandard conditions.

 

Electroplating

Heat of Vaporization

The amount of heat required to vaporize one gram of a liquid at its boiling point with no change in temperature. Usually expressed in J/g. The molar heat of vaporization is the amount of heat required to vaporize one mole of liquid at its boiling point with no change in temperature and usually expressed ion kJ/mol.

Adsorption

Adhesion of a species onto the surfaces of particles.

Acid Anhydride

Compound produced by dehydration of a carbonic acid. General formula is R--C--O--C--R. Chemical compound that reacts with water to form an acid and are usually oxides of nonmetallic elements.

Valence Bond Theory

Assumes that covalent bonds are formed when atomic orbitals on different atoms overlap and the electrons are shared.

Neutron

A neutral subatomic particle having a mass of 1.0087 amu.

Electron Affinity

The amount of energy absorbed in the process in which an electron is added to a neutral isolated gaseous atom to form a gaseous ion with a 1- charge, has a negative value if energy is released.
