The Bohr model of the hydrogen atom was the first atomic model to successfully explain the atomic hydrogen radiation spectra. Niels Bohr proposed the atomic… Read More
Energy, like matter, is always conserved, which means that it cannot be created or destroyed, but it can be converted from one form to another.… Read More
The oxidation states of the reactants change in redox reactions, which are oxidation-reduction chemical reactions. The term redox refers to the reduction-oxidation process. All redox… Read More
Thermodynamics is concerned with the ideas of heat and temperature, as well as the exchange of heat and other forms of energy. The branch of… Read More
Any group of chemical compounds in which hydrogen is joined with another element is called a hydride. On the basis of the type of chemical… Read More
The Valence Shell Electron Repulsion (VSEPR) model can predict the structure of most molecules and polyatomic ions with a nonmetal central atom; it can also… Read More
Previously, acids, bases, and salts were identified through the testing of their aqueous solutions. An acid is defined as a substance that causes a sour… Read More
The concept of hybridization is defined as the process of combining two atomic orbitals to create a new type of hybridized orbitals. This intermixing typically… Read More
Elements are arranged in a periodic table row-wise and column-wise according to similarities in their chemical and physical properties. The elements in the first column… Read More
Everything around us is a matter which has some physical and chemical properties. Matter around us exists in different states. For a matter to occur… Read More
The ideal gas law is a well-defined approximation of the behaviour of several gases under various situations in thermodynamics. The Ideal Gas Equation is a… Read More
Elements are arranged in a periodic table row-wise and column-wise according to similarities in their chemical and physical properties. The elements in the first column… Read More
The kinetic molecular theory of gases explains a gas’s three macroscopic characteristics in terms of the microscopic nature of the gas’s atoms and molecules. The… Read More
The modern periodic table is based on the law that an element’s properties are a periodic function of its atomic number. These properties are related… Read More
Every substance has its own set of characteristics. Physical and chemical properties can be used to classify these properties. Physical properties are those that may… Read More
