Quantum mechanical model

Molecular Geometry gives data about the overall state of the particle as well as bond lengths, bond points, torsional points and whatever other mathematical boundaries that decide the place of every molecule. In covalent particles, the bonds are directional because the common sets of electrons stay limited in a positive space between the nuclei of […]

The centre of an atom, the nucleus, was discovered by a famous physicist Ernest Rutherford in 1911. The term nucleus came from the Latin nucleus, which means “kernel” or “core,” a miniature of nux (“nut”). Therefore, the nucleus is a small, dense, positively charged region at the centre of an atom. The nucleus is the

Which stream to choose after 10th? The atom, according to Thomson’s model, is structurally similar to a plum pudding. He imagined electrons as dry fruits in a positive-charged sphere that represented the pudding. We can also compare this to a watermelon, with the positive charge dispersed throughout the edible part of the watermelon and electrons

Atomic model: The discoveries of the subatomic particles lead to the drive of curiosity on the arrangement of the atomic particles like electrons, protons and neutrons in atoms. Sir Joseph John Thomson was the first-ever person proposing the model for atomic structure to this world of science. After the discovery of negatively charged particles  or

Thomson’s discovery           Soon after J.J. Thomson discovered electrons, this research and experiments carried out on a cathode ray tube took place in 1897. But at this time, the nucleus was not yet discovered. This model was the first atomic model that came into existence and was published by the leading British science journal of the

The atom’s existence was first proposed in 400 BC by Indian Maharishi Kamaad and Greek Philosopher Democritus. According to them, on continuing the division of matter, a stage is reached beyond which further division is impossible. All matter comprises extremely small indivisible particles, Indian Manunshi Kamad and Greek Philosopher Democritus called this extremely small indivisible

Introduction In physics and chemistry, the wave nature of electrons is known as an atomic orbital. We can calculate the probability of finding an electron adjacent to the nucleus. The electron spin can be referred to as an indication of angular momentum as well as a quantum property of electrons. Electrons have an angular momentum

The atomic orbitals of an atom describe the most likely location for electrons to be found in and around the nucleus of the atom. At any given time, each orbital can only hold two electrons. In most cases, they are represented as three-dimensional space all around the nucleus, with numerous atomic orbital configurations. Aspects of

Atoms make up everything around us. They are the smallest unit of matter. Atoms have two major parts – the central nucleus containing protons (the positively charged particles) and neutrons (no charge particles), and the electron shells (outermost region) containing electrons (negatively charged particles).  Meaning of Rutherford’s Structure of Atom Physicist Ernest Rutherford developed this

Graphite is a crystalline form of carbon, typically occurring in metamorphic rocks as flakes or crystalline layers. It is formed by the metamorphosis of carbonaceous sediments. In nature, it is also found in igneous rocks, meteorites, and the mineral plumbago. Artificially, it can be prepared by heating powdered coke mixed with some sand and ferric
