1.	(1) The probability of finding an electron is maxium at certain places in space (2) Energy change takes place only during excitation or deexcitation of electron (3) Electron has both particle and wave nature (4) Angular momentum of the electron revolving in different ellipticals orbits is quantised Arrange the above statements of different models or principals in the chronological order , which ultimately led to the development of modern structure of the atom
Answer» 1,2,3,4 2,4,3,1 4,3,2,1 2,3,1,4 Solution :Energy CHANGE takes place only during excita-tion or deexcitation of electrons. Angular momentum of the electrons revolv-ing in different ELLIPTICAL ORBITS is quantised. Electron has both particle and wave nature. ltbrrgt The PROBABILITY of FINDING an electron is maxi- mum at certain places in space.
