Is brass a substitutional or interstital alloy?

 

Substitutional alloys have same sized components.

Interstital include small atoms fitting into space b/w large atoms.

like steel...

 

But for the alloy for brass, would I have to uncover the size of the copper and zinc in order to see whether they are interstital or substitutional

Thanks for the chart!

I think it might be substitutional because of the relative sizes of copper and zinc.

Correct The whole top row of transition metals, as you can see, are about the same size and many substitutional alloys are known between them. For example stainless steel is mostly iron, nickel, and chromium. Carbon is tiny by comparison, but has it's place in stainless steel as well, filling in some of the gaps between the Fe, Cr, and Ni.
