HOW CAN WE WRITE SUBSHELL ELECTRONIC CONFIGURATION? |
First of all we should know the increasing order of energy. ie 1s2s2p3s3p4s3d......... Also we must know that s-sub shell can have 2 electrons, p-sub shell can have only 6 e-, d-sub shell has 10e- etc. Then we can write electronic configuration of an element. e/g: Lithium, atomic no.=3 1s2,2s1 similarly Neon, atomic no.=10 1s2,2s2,2p6 |
