What is quantum mechanical model of atom give its important features.

Explanation

Quantum Mechanical Model of Atom : This model of atom is the picture of the structure of the atom which emerges from the application of the schrodinger equation to atoms
(i) the energy of electron in atoms is quantized for example when electrons are bound to the nucleus in atoms
(ii) the existence of quantized electronic energy levels is a direct result of the wave like properties of electrons and are allowed solutions of Schrodinger wave equation.
(iii) both the exact position and exact velocity of determine simultaneously (Heisenberg uncertainty principle ) .The path of an electron in an atom therefore can never be determined or knonwn accurately
(iv) An atomic orbital is the wave function w for an electron in an atom
(v ) The probability of finding an electron at a point within an aton is proportional to the square of the orbital wave function i.e., w density and is always positive
From the value of `w^(2)` at different point within an atom it is possible predict the region around the nucleus where electron will most probably be found.
