Please answer all of the questions below and explain properly.

Below is a table showing the atomic radius, crystal structure, electronegativity, and valence over a certain amount of elements. For the elements that are not metallic, only the atomic radius is shown. You will investigate what type of solubility each of these elements achieves with Nickel (Ni).

(Hint: arrange the elements according to the size of their atomic radius, starting from the atomic radius of Ni and see how much the other elements differ as a percentage.)

a)

Which of the elements goes completely into substitution solution with Ni?

b)

Which of the elements goes into partial substitution solution with Ni?

c)

Which of the elements go into complete addition solution (space positions or interstitial) with Ni?
