Atomic Orbital

Introduction Atomic orbitals are the three-dimensional spaces that surround the nucleus and are most likely to contain an electron. The atomic orbitals have been combined to create molecular orbitals. They obtain orbitals in quantum theory, some of which are electron shells in the s, p, d, and f configurations. Although orbitals come in a variety […]

Atomic Number & Mass Number

Introduction While the number of protons is merely the atomic number, the atomic mass of an atom is the sum of both its protons and neutrons. The letters A and Z can be used to denote these. Since it offers the key to the element’s existence, the atomic number is the concept that deals with […]

Bohr’s Atomic Model Postulates

Introduction In 1913, Neil Bohr introduced the Atomic Model, which was based on Planck’s quantum theory of radiation. In overcoming the limitations of Rutherford’s atomic model and describing the hydrogen spectral lines. One such model appeared to be very effective in describing the atom’s stability, as well as the line spectra of an H atom. […]

Calcination And Roasting

Introduction Calcination and roasting are two processes used to convert ores into oxides. Ores are a naturally occurring substance found in the earth’s crust. These ores are rich in minerals and valuable metals. Metals extracted from ore are required by applying lots of heat, either in the presence or absence of oxygen. Processes such as […]

Coal Products

Introduction We use a variety of materials for our necessities. Some are naturally occurring, while others are the result of human labour. Natural resources are plentiful as a result of the abundance of numerous resources in nature. Carbonization contributes significantly to global coal production. Coke is the primary by-product of high-temperature carbonization; approximately 4% of […]

Atomic Radius-An Overview

Introduction The distance between the nucleus’s core and the valence shell/outermost shell, known as the atomic radius of an element, serves as a benchmark for the size of its atom. The periodic table shows that the atomic size increases as you move down it and decreases as you move from left to right. The reason […]

Coal Story

Introduction Coal appears to be a dense carbon-rich substance that is brown/black and formed in layered sedimentary rock. This is one of the most important major fossil fuels. It is said to contain half of the total carbon-containing substance by weight generated by the compression and stiffening of modified plant residues, primarily peat settlements. Because […]
