Radioactivity and radioactive series

Radioactivity

Radioactivity is the phenomenon of spontaneous disintegration of certain nuclei into other elements with the emission of invisible active radiations.  It is a natural phenomenon in which unstable atoms emit radiation to achieve stability. Discovery In 1896 Henri Becquerel discovered … Read more

Crystals and laws of crystallography

Types of unit cell

In any compound, intermolecular forces of attraction and thermal force operate in opposite directions. The intermolecular force of attraction tends to keep the particles together while the thermal force tends to keep the particles apart. The extent of these forces … Read more

Kinetic Particle Theory

Kinetic Particle Theory

To understand the matter, one can employ the kinetic particle theory. And virtually everything around us is made of matter.  All matter is composed of numerous tiny particles that move randomly all the time. The matter is a substance that … Read more

Carbon Nanotube- Definition, Properties, and Applications

Carbon Nanotube

Carbon nanotubes (CNT) are the fundamental building blocks of nanotechnology. Nanotechnology heavily relies on carbon, which has an atomic number of six. While researching the graphite electrode surface used in electric arc discharge, Iijima unintentionally discovered them. This unintentional discovery … Read more

Organosilicon Compounds- Preparation, Properties, Uses

Organosilicon Compounds

Organosilicon compounds are organometallic compounds that contain Si-C bonds. As the Si-C bond is extremely hard and stable, many organosilicon compounds containing Si-C have been synthesized. However, silicon has little tendency to form a bond with itself and does not … Read more

Aromatic Nucleophilic Substitution Reactions with Types

Aromatic Nucleophilic Substitution Reactions

An aromatic nucleophilic substitution reaction is the replacement of hydrogen or substituent on an aromatic ring by a nucleophile. Aromatic rings do not undergo the aromatic nucleophilic substitution reaction under ordinary conditions. The reason for this low reactivity of the … Read more

Coordination compounds and their isomers with Identification

Coordination position isomers

Coordination compounds are complex compounds consisting of a central metal atom surrounded by nonmetal atoms or groups of atoms called ligands that are chemically linked to it. E.g., Ā [Co(NH3)6]Cl3, [CoCl(NH3)5]Cl2 Isomerism in Coordination compounds Isomers are compounds that have the … Read more
