The compound in human bones is CaC $O_{3}$ .

This is an ionic compound, and the negative ion here is C $O_{3}$ .

Number of bonds = 4

Number of atoms around central atom = 3

Implying bond order = $\frac{4}{3}$ = 1.33

I thought the main component in bones was calcium phosphate?

Calcium Phosphate and Calcium Carbonate are both components of human bones. I have edited the question to ensure that only Calcium Carbonate will be considered.

Thanks for pointing that out.

A bone is 30% organic and 70% inorganic. The organic portion is protein; the inorganic portion is the mineral hydroxyapatite, which is a combination of calcium phosphate, calcium carbonate, calcium fluoride, calcium hydroxide, and citrate. The protein, which is mostly collagen, provides strength and flexibility to the bone whereas the hydroxyapatite gives the bone its rigidity and solid structure.
