Answer 2

Answer:

Electronic Configuration :

For Iron :

• The Electronic configuration of the element Fe (Iron) is 2,8,8,8.

• Iron (II) that is, ferrous has a valency 2.

• Iron (III) that is, ferric has a valency 3.

• The element Iron has 26 protons and 30 neutrons.

For Copper:

• The Electronic configuration of the element Cu (Copper) is 2,8,8,18,1.

• Cu (I) that is, cuprous has a valency 1.

• Cu (II) that is, Cupric has a valency 2.

• The element Copper has 29 protons and 35 neutrons.

What is Electronic Configuration?

• Distribution of electrons in different orbits or shells is called electronic configuration.

• The distribution of electrons into different shells (also called as orbits) of an Atom was suggested by Bohr and Bury.

• The atoms of different elements contain different numbers of electrons , protons and neutrons.
