Most Popular

Atomic Number


Integral number of protons in the nucleus, defines the identity of element.
 

Absolute Zero

The zero point on the absolute temperature scale, -273.15°C or 0 K, theoretically, the temperature at which molecular motion ceases. The concept of an absolute zero temperature was first deduced from experiments with gases. When a fixed volume of gas is cooled, its pressure decreases with its temperature. Absolute zero physically possesses quantum mechanical zero-point energy.

Active Metal

Metal with low ionization energy that loses electrons readily to form cations.

Molecular Orbital Theory

A theory of chemical bonding based upon the postulated existence of molecular orbitals.

Group

A vertical column in the periodic table, also called a family.

Electrodes

Surfaces upon which oxidation and reduction half-reactions, occur in electrochemical cells.

Polydentate

Refers to ligands with more than one donor atom.

Periodic Table of Elements

An arrangement of elements in order of increasing atomic numbers that also emphasizes periodicity.

Avogadro's Number

The number (6.022x10^23) of atoms, molecules or particles found in exactly 1 mole of substance.

Saturated Solution

Solution in which no more solute will dissolve.
