he atomic number of an atom A is x. Valence elec tronic configuration

1.	he atomic number of an atom A is x. Valence elec tronic configuration of another atom B is 6s^25d^3 and its atomic number is (x + 5). Write the elec-tronic configuration of A.
Answer» Solution : 's'- orbital is spherically symmetrical and non DIRECTIONAL. Hence, there is no NODAL plane. Only a spherical region adjacent to the orbital where the probability of FINDING an electron is zero is found, which is CALLED nodal region.'p'orbital is dumb bell shaped and directional and lies along the axis. Hence, for each p-orbital, there is one plane where the probability of finding an electron is zero
