Question

Atomic number of iron (Fe) is 16

a) Write it's subshell electronic configuration.

b) To which group and block of the period table does iron belong.

c) What is the oxidation state Fe in Fe2O3 ( oxidation state of oxygen is -2

d) Write down the subshell electronic configuration of the Fe iron with this oxidation state ​

Answer 1

Answer:

A. Electronic configuration of iron in shells

All of these shells are filled except the 3p shell which has four electrons. Therefore, the electronic configuration of sulfur can be written as 1s2 2s2 2p6 3s2 3p4.

B. group 8
