Some Basic Properties of the Halogens – Group 17
The Halogens exhibit some very interesting properties in the periodic table. Elements typically become more metallic or basic on descending a main group. Thus in…

Properties, Allotropes and Uses of Phosphorus
Phosphorus is a non-metallic element that belongs to group 5 of the periodic table. It does not occur free in nature due to its very…
How to Produce Trans-Uranic Elements By Particle Bombardment
Uranium has the highest atomic number of any naturally occurring element and was, for a long time, placed at the end of the periodic classification…
Principles of Nuclear Fusion in the Making of a Hydrogen Bomb
When a uranium atom is split into or more atoms of medium relative atomic mass, there is a decrease in mass and a corresponding release…
How Equilibrium is Maintained in a Reversible Reaction
We shall now study dynamic equilibrium in reversible chemical reactions since it has many industrial applications. Some reactions can be made to go either way,…
Polymorphism and Examples of Polymorphic Compounds
Polymorphism describes a situation whereby substances can crystallize in more than one form. Such substances are said to be polymorphic. If the number of crystalline…
Three Important Methods of Separating Isotopes
Separating Isotopes is a chemical process that is hinged on the difference in mass of these isotopes. As isotopes have the same chemical properties, their…
Isomorphism and the Characteristics of Isomorphous Compounds
Substances which from very closely related crystals are said to be isomorphous, but it is not always very easy to decide when two substances are…
Application of Mass Spectrometer in Detecting Isotopes
Investigation of radioactive disintegration series shows that more than one element can occupy the same position in the periodic table. Such elements must have the…
The Role of Molecular Orbitals in Atomic Reactions
What are Molecular Orbitals? It is clear that ions are held together by electrostatic attraction in an electrovalent or ionic bond, but it is less…
