barr, average distance also described as expectation value ofthe distance of the electron from the nucleus is different from r_(max). For 1s orbital of H-atom, r_(max)=a_(0), barr=3/2a_(0). For 2s orbital of H-atom r_(max) =0.77a_(0) "and" 5.23a_(0). Find barr"for"r_(max) = 5.23a_(0). Also find barr_(2) for 1s orbital of Li^(2+) ion. Hence find the value of ((barr_(1)xxbarr_(2)))/(a_(0)^(2)).

1.	barr, average distance also described as expectation value ofthe distance of the electron from the nucleus is different from r_(max). For 1s orbital of H-atom, r_(max)=a_(0), barr=3/2a_(0). For 2s orbital of H-atom r_(max) =0.77a_(0) "and" 5.23a_(0). Find barr"for"r_(max) = 5.23a_(0). Also find barr_(2) for 1s orbital of Li^(2+) ion. Hence find the value of ((barr_(1)xxbarr_(2)))/(a_(0)^(2)).
