Question

Can any1 explain me hw to write the electronic configuration??? In brief (points).......... Rpl fast..........

Answer 1

1 write down the electrons,protons,neutrons separately.
2 check the electrons i.e the no of electrons.
3 write the frequeny distribution i.e if e=12: 2,8,2
4 draw the k,l,m shells as required
5 in the nucleus write n=whatever,p=whatever.

Answer 2

first note d atomic no. of d element .--. atomic no denotes d no of electrons present in d element --- now we hav k, l ,m ,...shells wid us..--- capacity of k to hold electrons is 2..--- capacity of l to hold electrons is 8..--- n so of m is also 8........--- now ........lets take d ex of carbon...--- its at. no. is 6. ---- thus ,.......k shell will obtain 2 electrons n d remaining 4 will take der positions in l shell.
