The radial distribution function [P(r)] ...

The radial distribution function `[P(r)]` is used to determine the most probble radius, which is used to find the electron in a givenorbital. `(dp(r))/(dr)` for `1s`- orbital of hydrogen like atom having atomic number Z, is `(dp)/(dr)=(4Z^(3))/(a_(o)"^(3))(2r(2Zr^(2))/(a_(o)))e^(-2zr//a_(o)):`
Then which of the following sttements is/are correct ?

A

At the point of maximum value of radial distribution function `(dp(r))/(dr)=0,` one antionde is present

B

Most probable radius of `Li^(2+)isa_(o)/(3)"pm"`

C

Most probable radus of `He^(+)isa_(o)/(2)"pm"`

D

Most probable radius of hydrogen atom is `a_(o)` pm

Bohr's model of hydrogen atom In order to explain the stability of atom and its line spectra, Bohr gave a set of postulates: An electron in an atom revolves in certain circular orbit around the nucleus. These are the orbits for which mvr=(nh)/(2pi) In these allowed orbits, the electron does not radiate energy. When an electron jumps from higher energy level E_(n_2) to lower energy orbit E_(n_1) , radiation is emittd and frequency of emitted electron is given by v=(E_(n_2)-E_(n_1))/h .
