Atomic Structure

Erwin Schrödinger developed the concept of the electron cloud. He developed an equation that can calculate the probability of finding an electron in an area around the nucleus. An electron cloud is a group of electrons that circulate the nucleus. Electrons are most likely to be found in the electron cloud. The higher density of […]

Atomic theory was first proposed by John Dalton, an English physicist and a chemist of the 19th century. He was born in England on September 6, 1766.  His work, Meteorological Observation, and Essays contained many original ideas of his and his friends and was published in 1793. This book created a significant shift in meteorology

The Davisson and Germer Experiment was the first to prove that electrons are waves and to validate the de Broglie equation. In 1924, De Broglie hypothesized the dual nature of matter, but Davisson and Germer’s experiment did not validate the conclusions until much later. The findings proved quantum mechanics for the first time in an

Introduction A solid material where components like atoms, molecules, or ions are organised in a definite and sequentially organised over a vast distance in the crystal lattice is called Crystalline Solids.     Crystalline Solids : Structure Crystalline solids have definite sides and faces with specific melting points.The study of the geometrical structure in the crystal lattice

Atomic radius is the distance from the nucleus to the outermost orbital of an atom. We can grasp the concept by comparing it to a circle’s radius. The centre of the circle is the nucleus here. There are three types of atomic radii- Covalent radius, Metallic radius, and Ionic radius. Suppose a covalent bond is

In the electromagnetic spectrum, we have different kinds of radiation ranging from cosmic rays to radio waves. X-rays also constitute the EMR spectrum, and they are characterised by high energy frequency and low wavelength. Their wavelength is 10-8 to 10-12 metres, about the size of an atom. They are produced when a high-speed electron collides

The cathode ray tube, also known as the vacuum tube, contains one or more electron guns. The beams from the guns are manipulated to produce images on a glowing screen. The images may be electrical waveforms (oscilloscope), pictures (TVs, computer monitors), sonar targets, or other forms.  Dalton’s Atomic Theory A British schoolteacher named John Dalton

Atomic structure      Along with J.J. Thompson, there were other scientists such as Rutherford, Bohr, Dalton and Planck who formulated theories and explanations about the shape of an atom. Thompson was the first scientist to share his knowledge about the atomic structure. He defined how the atom appeared like a watermelon in which the crimson, fleshy

After combining all elements of physics, chemistry, and mathematics, the scientists came up with a scientific explanation of the basic unit of matter which is the atom. The theory that all matter is made up of atoms as their building blocks are known as the atomic theory. After that various scientists proposed their own theory

A tiny unit of every known matter that ends up as a chemical element comes under the term of an atom. It has a size of around 100 picometres. Most of the atom’s mass is because of the nucleus. An atom is made up of a nucleus (in the middle or centre) that has neutrons
