Atomic and molecular masses

Solid is a state of matter in which the constituting particles are arranged very closely. The constituent particles can be anything atoms, molecules or ions. Solid is one of the Four fundamental states of matter . The molecules in a solid are closely packed and contain the least amount of kinetic energy. We will study […]

We can determine the location of electrons and nuclei of an atom with molecular geometry and with the help of location of electrons and nuclei we can determine the shape of molecules. for example – H2O (water) We know about the location of electrons and nuclei in molecules of water then we can easily determine

It is not necessary to use a capital letter when writing the full names of the units, even if they are named after famous scientists. For example, newton, watt, ampere, and metre are all units of measurement. The unit should be written either in full or only using the symbols that have been agreed upon.

Molecule’s shapes can be predicted by looking at the electron pairs that surround the atoms in the center. In 1940, Sidgwick and Powell proposed the theory. On the basis of the VSEPR theory, the molecule is assumed to have a form that minimizes valence shell electronic repulsion. An electron pair repulsion exists in every atom,

An atom emits alpha, beta and gamma particles during radioactivity as unstable atoms try to reach a stable state. As a result, the atom decomposes by emitting a particle. This decaying process continues until the nucleus achieves stability. Mainly three types of radiation are emitted. These include alpha, beta and gamma rays. The atom’s nucleus

There are various postulates that we study in chemistry. A postulate is also called an axiom. These are those statements that are accepted by the world without any proof needed. These are the basic structures that are used to derive the theorems that are used now. When we develop any theory, any number of postulates

A polar molecule has one end that is slightly positive and the other that is slightly negative. Polarity in the molecule is a diatomic molecule with a polar covalent bond. Poles are the electrically charged locations on one side of the molecule, similar to the north and south poles of a magnet. A dipole is

A physical quantity is the property of a material or the system that can  be quantified by measurement. It can be presented as a value, which is the multiplication of a numerical value and a unit. It possesses at least two properties.  A numerical or number magnitude. The unit in which it is calculated.  Some of the physical quantities must be more fundamental than

The term unit refers to the amount or magnitude of any physical portion that is measurable. Different units are accustomed to indicating other measurements of particular types of quantities. Many physical quantities are measured to experiment, and many material amounts form the basis of mathematical equations. To measure material such amounts, appropriate and unique units

In chemistry, an orbit is a specified path with a regular form, along which electrons rotate around their axis. This electron revolution is also caused by the attraction of electrons towards the nucleus, which is discussed in more detail below. According to Bohr’s concept, the initial shell of an atom should include just two atoms
