Question

Indicate the electronic configuration of ions along the series

Answer 1

electronic configuration is the number of shells in which there are electrons
nucleus has an outer covering of shells in which electrons are present
the shells are K L M N and so on
and they have a fixed energy level like K shell can hold 2 electrons in maximum
similarly L shell can hold 8 electrons
M can hold 8 electrons and

and N can hold 16 electrons and so on ..




electronic configuration of Mg
is it has atomic number 12 so
the number of electrons is 12
so the electronic configuration is 2 , 8 ,2
where first cell contain two electrons second cell contains 8 electrons and a third contains two electrons

Answer 2

ELECTRONIC CONFIRGURATION
#########################
It is the number of shells in which electron has an outer layer
Thses contains 4 shells
K shell
L shell
M shell
N shell
In this the K shell can hold 2 electrons maximum
L she'll can hold 8 electrons
M she'll can hold 8 electrons
N shell can hold 16 electrons
