An atomic orbital may be defined as the three dimensional space around the nucleus within which the probability of finding an electron of given energy is maximum. where ψ is the amplitude of the wave where the coordinates of the electrons are( x,y,z) ,E is the total energy of the electron, V is its potential energy, m is the mass of the electron and h is the Planck’s Constant. In short Schrodinger wave equation is written as. Subscribe to the OCW … Your email address will not be published.

These values of energy corresponds to the energy levels which the electron in an atom can occupy. Postulates of quantum mechanics I : L10: Postulates of quantum mechanics II : L11: Classic harmonic oscillator : L12: Quantum harmonic oscillator (PDF - 2.1 MB) Note supplement 1 (PDF - 1.1 MB) Note supplement 2 . The wave function for an electron in an atom is called orbital wave function or atomic orbital.Since an electron can have any wave function ,therefore, there are many atomic orbitals in an atom.
For the wave motion of the electron in the three dimensional space around the nucleus, he put forward an equation known as Schrondinger wave equation. Author of this website, Mrs Shilpi Nagpal is MSc (Hons, Chemistry) and BSc (Hons, Chemistry) from Delhi University, B.Ed (I. P.

Quantum Mechanics Principles Steps Toward Quantum Theory Photoelectric Effect The following notes introduce Quantum Mechanics at an advanced level addressing students of Physics, Mathematics, Chemistry and Electrical Engineering. The electron spends most of its time in the volume of Sphere bounded by that distance and for rest of the time, the electron can be found outside the volume of the sphere. In case of light or sound, the square of the amplitude of the wave at any point gives the intensity of the sound or light at that point, Similarly the square of the amplitude of the electron wave ie ψ2 at any point gives the intensity of the electron wave at that point which in view of Heisenberg Uncertainty Principle means probability of finding the electron at that point. Probability provides the best possible description of a situation which cannot be described with certainty. It is the foundation of all quantum physics including quantum chemistry, quantum field theory, quantum technology, and quantum information science.. Application of Schrodinger Wave Equation to hydrogen atom. Quantum mechanics is a fundamental theory in physics that provides a description of the physical properties of nature at the scale of atoms and subatomic particles. where ψ is the amplitude of the wave where the coordinates […] 2)These quantized values of energy are obtained from the solution of Schrodinger Wave Equation. For the wave motion of the electron in the three dimensional space around the nucleus, he put forward an equation known as Schrondinger wave equation. Quantum mechanics has played an important role in photonics, quantum electronics, and micro-electronics. This space around the nucleus is called orbital .Wave function Ψ is called orbital wave function or atomic orbital. When Schrodinger Wave Equation is solved for hydrogen atom, the solution gives possible values of the energy ( E ) . Features of quantum mechanical model of atom. But many more emerging technologies require the understanding of quantum mechanics; and hence, it is important that scientists and engineers understand quantum mechanics better. The solution of Schrodinger wave equation for an electron in an atom gives the value of E and Ψ .The value of E represents the quantised value of energy which the electron in the atom can have. represents second derivative of Ψ w..r.t. x. The region of space around the nucleus which describes the probability of finding an electron of given energy in terms of dots is called an electron cloud.
