Document Summary

I , 2,3 , . n - atom are : (cid:8869) r = 3. 29 . En = -znh n = i , 2,3 . The and quantum number shells labels the that specifies the energy of an e in a hydrogen atom of an atom ; given by integer n lowest possible energy , Bohr radius finding radius of chance of of electrons in atoms ; the region in space where there is a electron an lowest energy orbital in hydrogen ; ao = 4ieoh_ = 52. 9 pm. N specifies the energy of the orbital j also an indicator of the shell. 1 for a given n ie n =3. These indicate the subshells of each level energy. This quantum number can be used to find the orbital angular momentum. There are 21+1 different values of m , This quantum number specifies the for a given direction of. The combination of the quantum numbers specifies an orbital.
