Can we decide the atomic number by given valence electrons in electronic configuration like 2s2 2p3 corresponds to Nitrogen but how ?

#2

Yes we can decide the atomic number by see the Valence electronic configuration. We have to write the electronic configuration of element by the given Valence electronic configuration and then count the total number of electrons which is equal to the atomic number.
