Question

Electronic configuration kaise kaise krte hai?(mine Fe3+ krke dikhao)​

Answer 1

Answer:

Hi bro first take the all electrons for example.

atomic number of sodium is 11 so in first shell(k shell) we take 2 electrons, in second shell(l) we take 8 electrons and in third shell(m shell) we take 18 electrons.

Now electronic configuration of sodium 2,8,1[in last shell there is only one electronic so we take only the remaining electrons.

Explanation:

Now,

Atomic number of Fe³+ is 23.

Therefore in first shell we take 2 electrons. then 8 then 8 and then 5

total= 2+8+8+5=23

so electronic configuration of fe3+ is: 2,8,8,5

hope it helps you.
