1.	Configurations Designations of sotne orbitals are given below. Identify those configurations that are not possible in an atotn. Arrange the orbitals with possible configurations in the order in which they are filled with electrons 6s, Sp, 7s, 4d, 2p, 3d, 3f, 4f, 1p.
Answer» Solution :1P and 3f are the configurations that are not possible for any orbitals in an atom. All others are possible. The orbitals are occupied by ELECTRONS in increasing ORDER of their ENERGIES. The order of energy is decided by n + e rule. n + l VALUES of orbitals . `6 rarr 6+0=64 d rarr 4+2=6 , 4p rarr 4+1 =5 2p rarr 2+1 =3,` `8 prarr 8+1 =9 3d rarr 3 +2 =5, 7s rarr 7+0 =74f rarr 4+3=7` `2p lt 3d lt 4p lt 6s lt 4f lt 7s lt 8p`
