Question

what is the valency of Nickel?? ​

Answer 1

Answer:

✅Verified Answer✅

Nickel (Ni) has the atomic number: 28

Nickel (Ni) has the atomic number: 28The electronic configuration of Ni : [Ar] 3d8 4s2

Nickel (Ni) has the atomic number: 28The electronic configuration of Ni : [Ar] 3d8 4s2Hence Nickel will 2 electrons from the s shell hence will show valency 2

Nickel (Ni) has the atomic number: 28The electronic configuration of Ni : [Ar] 3d8 4s2Hence Nickel will 2 electrons from the s shell hence will show valency 2But nickel is a transition element, hence it shows variable valencies like 2, 3 and 5 when it forms a complex.

$\huge\boxed{\underline{\mathcal{\red{A}\green{N}\pink{S}\orange{W}\blue{E}\pink{R}}}}$

• For nickel it would be 4s2 so resulting +2 valency by giving both the s-electrons away. Nickel generally shows +2 oxidation state. Hence, the valency of Nickel is 2.
• However, nickel also shows a valency of zero, 1, 3 and 4 in some compounds.
