Question

What type of bond is present between two atoms of zinc in a nickel

Answer 1

Answer:

Pure covalent

Explanation:

To know the type of bond between two atoms you must find the electronegativity difference of them:

If electronegativity difference is:

< 0.4: Pure covalent.

Between 0.4 and 1.8: Polar covalent.

> 1.8: Ionic.

The electronegativity of Zn is 1.65 and Ni is 1.91. Electronegativity difference is:

1.91 - 1.65 =  0.26

That means the type of bond is:

Pure covalent
