Question

How does the electronic configuration of ions vary with the configuration of their isoelectronic atoms. Explain by taking two examples. Indicate the electronic configuration of ions along the series

Answer 1

Electronic configuration is the electrons filled in shells..... Shells r outer covering of nucleus, shells r K, L, M, N
In K shell.. 2 electrons filled
In L shells.. 8 electrons filled
In M shell.. 8 electrons filled

Eg.. Electronic configuration of Mg
Ato. no. of Mg.. 12... So, in K shells 2 be filled, in L shell 8 be filled.. n in M shell 2 electrons remains
Mg... 2, 8, 2....


Hope this is helpful..
