What was the basis for the origin of the concept of an atomic model? Define atomic orbital.
The basis for the origin of the concept of an atomic model is as follows,
Heisenberg Uncertainty Principle: According to Heisenberg Uncertainty Principle it is impossible to determine simultaneously and accurately the exact position and the momentum of the moving particle.
Dual nature of Electron: de Broglie derive an expression for calculating the wavelength of the wave which is associated with the moving electron.
The expression is called the De Broglie equation.
The dual nature of electron is particle nature, as well as wave nature, was established by the equation.
Atomic Orbital: three-dimensional regions in space around the nucleus where the probability of finding an electron with killer energy is maximum is called an atomic orbital
Schrodinger's wave equation:
On the basis of the Schrodinger Wave Equation, the quantum mechanical model of the atom has been proposed. In this model, the state of an electron in an atom can be explained with respect to four quantum numbers. these three quantum numbers namely the Principal Quantum Number azimuthal quantum number and a magnetic quantum number have been derived from Schrodinger Wave Equation.
