TOPICS Hybridization Valence bond theory is based on the theory that describes how orbitals overlap in molecules to form bonds. Valence bond theory describes a chemical bond as the overlapping Read More.. Ideal Gas Law An ideal gas is a concept that was developed to study the behavior of the real gas. The concept was first coined by Emile Clapeyron in 1834 as a combination of the empirical Read More.. VSEPR - Theory This theory was developed by Gillespie and Nyholm. Valence shell electron pair repulsion (VSEPR) theory is a model used in chemistry to predict the geometric arrangement of the atoms or Read More.. Hund’s Rule The Aufbua principle successfully explains that how the electrons first fill the lowest energy orbitals, and then move on to higher energy orbitals only after filling the lower energy orbitals. Read More.. Pauli’s Exclusion Principle In 1925, an Austrian physicist Wolfgang Pauli proposed the Pauli’s exclusion principle, these principles describes the properties of electrons in an atom. The Pauli’s exclusion principle states that Read More.. Collision Theory Have you ever created fire with flint stone? Perhaps many of you might have, maybe in one of your school camp or during your wild camping trips. What we see here is, fire is created by Read More.. Bohr’s Atomic Model Bohr Atomic Model, the atomic model proposed by Danish physicist Niels Bohr in 1913, was a modification of the earlier Rutherford’s atomic model, for which it is also sometimes called Read More.. Factors Affecting Reaction Rates The rate of a reaction can be defined as the measure of the change in the amounts of the reactants involved and the amounts of the products Read More.. Thomson’s Atomic Model | Plum Pudding Model We all have electricity in our home; the electricity that we use in our daily life is actually a constant stream of tiny particles called as electrons, Read More.. Activation Energy Every one of us must be aware of the fact that on turning the vehicle key, the vehicle gets started but, here the key that we turn causes a spark, that spark activates or initiates the burning of Read More.. Non-Ideal Gas Behavior You have perhaps learned about the ideal gas law, which is an equation for the state of a hypothetical gas. But what about the real gas which is a non-hypothetical gas and where every gas Read More.. Van Der Waals Equation The ideal gas law treats the molecules of any given gases as a point mass having perfect elastic collision and there is no intermolecular attraction or repulsion between the Read More.. Molarity Most matters we find around us are the mixture of different substances. These matters physically combine with two or more components to form itself in nature. A glass of milk with added Read More.. Sublimation in Chemistry Any matter that exists around us could be in either of the four phases - solid, liquid, gas and plasma. We can see that matters can change from a present state to another with the change in Read More..
