Represent graphically, the variation of probability density `(psi^2 _(r))` as a function of distance (r ) of the electron from the nucleus for 1s and 2s orbitals.

Represent graphically the variation of magnetic field with distance from a long current carrying wire.

Statement 1 : The plots of probability density and radial probability function versus distance r from the nucleus for any particular orbital are not identical, Statement 2 : Probability density is psi^(2) whereas radial probability function represents probability of finding the electron in a shell of thickness dr.

The values of orbital angular momentum of the electrons in 1s, 2s, 3d and 2p are

Discuss the similarities and differences between a '1s' and a '2s' orbital.

The variation of potential with distance R from a fixed point is as shown in the figure. The electric field at R = 5 m is

For an electron in a hydrogen atom, the wave function psi is proportional to exp -r//a_(0) , where a_(0) is the Bohr radius. Find the ratio of probability of finding the electron at the nucleus to the probability of finding it at a_(0) .

For an electron in a hydrogen atom, the wave function y is proportional to exp- r//a_(0) , where a_(0) is the Bohr radius. Find the ratio of probability of finding the electron at the nucleus to the probability of finding it at a_(0) .
