" The most probable radius (in "Pm" ) for finding the electron in He" is: "

Assertion : The energy of an electron is mainly determined by principal quantum number. Reason : The principal quantum number is the measure of the most probable distance of finding the electron around the nucleus.

The probability of finding the electron in the orbital is

(A) : The energy of electrons is largely determined by its principal quantum number. (R) : The principal quantum number is a measure of most probable distance of finding the electron around the nucleus

For an electron in a hydrogen atom , the wave function Phi is proportional to e^(-r/a(0)) where a_(0) is the Bohr's radius What is the radio of the probability of finding the electron at the nucleus to the probability of finding at a_(0) ?

The probability of finding electrons in de orbital is:

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) .
