Explain why the Crystal Field Theory is not applied to complexes of main group metals ?

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?

Find the pH in which the hydrogen ion concentration is 6.38*10-6 mol/dm-3

Differentiate between the covalent radii and the ionic radii. Name the cations that are largest single atom cations. Which out of N3– and O2– ion is bigger in size and why?

What is binding energy? What are the effects of Beta-decay, beta+- decay,abd electron capture on the atomic no.z and the mass no.A of the parent atom?

Calculate the entropy change when 36 g of ice is heated at standard pressure from 230 K to 320 K. Take the molar heat capacities at constant pressure, Cp,m, of water and ice to be
75.3 and 37.7 J mol 1 -1 respectively, and the molar enthalpy of fusion of ice to be 6.02 kJ mol-^. The molar mass of water is 18.0 g mol-1, and ice melts at a temperature of 273.15 K
