Answer to Question #77322 in Inorganic Chemistry for Surabh K.T

Question

consider a Be atom.Its electronic configuration is given by 1s2,2s2.I read that both the electrons of the 2s orbital will have the same energy.But the 2s orbital is spherical in shape.Hence we can say that it occupies a spherical volume around the nucleus.Suppose the 2 electrons are present at different places in that spherical volume i.e the distance of both electrons from the nucleus is different and hence they should have different energies.where am i going wrong?
