Design Alien Skeleton w/ Copper, Calcium & Element: Tip?

[Yemmy]

Could calcium and copper and say - boron, be joined into one substance?
If not boron, then which element?
I am trying to design an alien skeleton with copper, calcium, and ?
I love copper and part of the idea is its distribution throughout the universe.
I am asking for a tip about where to look for this info, unless someone out there has element mixing knowledge resting on the tip of their brain.
Thank you.

You can mix basically all metals together, and smaller amounts of nonmetals inside are possible as well. Not everything will lead to properties you want for bones (chemically passive, reasonable melting point, high structural strength, not too heavy, ...), and not everything will be useful for life (available in the environment, suitable chemical pathways to produce it, ...) but in a fictional setting there is more freedom in the parameters.

It is not possible for calcium, copper, and boron to be joined into one substance. These elements have different atomic structures and cannot combine to form a single substance.

If you are looking for another element to incorporate into your alien skeleton design, you could consider using sulfur. Sulfur is commonly found in the universe and has a similar atomic structure to both calcium and copper, making it a possible candidate for a third element in your design.

As for where to look for information on element mixing, you could try researching the properties and characteristics of different elements and their potential for combining with other elements. Chemistry textbooks and online scientific databases could also be helpful resources.
