Question

What is the valency of iron?​

Answer 1

❤HELLO

IRON HAS VALENCY 2 AND 3 BECAUSE

iron having atomic number 26. It has two electrons in its 4s orbital and 6 electrons in its 4d orbital. In order to attain stability it looses it two electrons in the 4s orbital and hence have +2 valency and since the half filled orbitals are more stable it loses one more electron from d orbital and has +3 valency.
