Lewis Structure

Lewis Structure is defined as an easy and simple representation of valence shell electrons or valence electrons in a given molecule. Used in demonstrating how electrons are classified and arranged throughout the individual atoms in a given molecule. Electrons are displayed in the form of “dots” or for bonding any electron; it’s showcased by lines … Read more

Covalent bond

The covalent bond, also known as the molecular bond is the interatomic linkage which is the outcome from electron pair sharing between the two atoms. Or simply you can say that it refers to the chemical bond which includes electron pair sharing between atoms. The sharing of these electron pairs is called the bonding pairs, … Read more

Ionic bond

  Ionic Bond is also known as Electrovalent Bond. It’s a kind of linkage composed with the help of electrostatic attraction in between charged ions that are opposite in nature, relating to a chemical compound.   Such bond is formed when outer shell electrons or valence electrons of a single atom are permanently transferred to … Read more

Density of Unit Cell

  Definition of Unit Cell The smallest group of atoms which has the overall symmetry of a crystal, and from which the entire lattice can be built up by repetition in three dimensions is termed as Unit Cell. Crystalline solids exhibit a regular and repeating pattern of constituent particles. The diagrammatic representation of the three dimensional arrangement … Read more

Basic Concepts of Chemistry

General Introduction: Chemistry is the science of molecules and their transformations. It is the science not so much of the one hundred elements but of the infinite variety of molecules that may be built from them.   ~Roald Hoffmann Chemistry is the study of matter and the ways in which different forms of matter combine … Read more

Unit Cell And Space Lattices

The smallest group of atoms or molecules, whose repetition at regular intervals in three dimensions produces a crystal, is called as a Unit cell. Hence, a unit cell is the smallest portion of a crystal lattice which, when repeated in different directions, generates the entire lattice. Each unit cell is defined in terms of lattice points – the … Read more

Nature of Matter

We are all familiar with the matter. The definition of Matter is anything that has mass and volume (takes up space). For most common objects that we deal with every day, it is fairly simple to demonstrate that they have mass and takes up space. Everything that is around us including the pen, book, pencil, buildings, … Read more
