Do you know !! What is resonance theory? Resonance Theory: According to resonance theory some molecules are represented by two or more than two structures and the actual structure is weighed average […]
Do you know !! Theories of Covalent Bonds: There are three theories of covalent bonds. These are (i) VSEPRT, Resonance Theory, (ii) VBT and (iii) MOT. Valence Shell Electron Pair Repulsion […]
Electronic Configuration: The distribution and arrangement of electrons in various shells, sub-shells and orbitals is called electronic configuration. Electronic configuration follows three rules. Auf Bau Principle: It states: “Electrons occupy shells in […]
Shapes of Orbitals: Shapes of orbitals are obtained by probability contours. If we plot probability of finding electrons versus distance from nucleus, we see that probability is zero at the nucleus it […]
Do you Know !! What is Quantum Number ? These are certain numbers which are used to locate electron in an atom or in other words these are address of electron. They […]
Schrodinger Wave Equation: In 1926, Erwin Schrodinger, a Austrian Physicist, developed an equation, which is given below and is called Schrodinger equation. Where E = total energy of electrons V = […]
Heisenberg’s Uncertainty Principle: In 1927, Warner Heisenberg proposed the uncertainty principle. It states: “It is impossible to state both position as well as momentum of electrons accurately and simultaneously” To determine the […]
Important Applications of Broglie’s Hypothesis: De Broglie’s hypothesis is good enough to explain Bohr’s postulates. Bohr’s theory states that electron revolves only in orbits of particular radii and in an orbit […]
Do you know ! You can easily find excess and limiting reactants Firstly , you must know that !! What is Limiting reactant and excess reactant? Limiting Reactant Definition: The reactant which […]
Louis de Broglie’s Hypothesis: (Dual nature of radiations) There arose a conflict about the nature of radiations. There were two schools of thoughts: (i) wave nature and (ii) particle nature […]
