SUBJECT-CHEMISTRY

CHAPTER-ATOMIC STRUCTURE

SUBTOPIC- Schrodinger wave equation, orbit and orbital concept.

KEY NOTES :

 The branch of science that takes into account this dual behaviour of matter

is called quantum mechanics.

 Schrodinger wave equation is based on it.

 He was able to explain the movement of electron in three dimensional

space around the nucleus.

The equation can be written as

         8 m ( V )  0

E
x 2 y 2 z 2 h 2

Where Ψ is the wave function

x, y, z are Cartesian coordinates.

m is the mass of electron

E is the total energy

V is the potential energy

H is the Planck's constant

 This equation can also be written as ĤΨ = EΨ

Where Ĥ is Hamiltonian operator
