Answer 2

hi
it is nothing but distributing the electrons according to the shell. all u need to know is the atomic number.
in k shell we will only have a maximum of 2 electrons
in L shell there will be 8 electrons
in m shell there are supposed to be 18 electrons but due to the capablity of sub shells there are only 8 electrons in M shell.
