Summary

Calcium, phosphorus, oxygen, and fluorine atoms for construction of Apatite (Fluorapatite \ Ca5(PO4)3F) ball-and-stick model.
Fluorapatite is found in the teeth of sharks and other fishes in varying concentrations. It is also present in human teeth that have been exposed to fluoride ions, for example, through water fluoridation or by using fluoride-containing toothpaste. The presence of fluorapatite helps prevent tooth decay or dental caries.

Model sizes (diameters):
Calcium - 21.4 mm; Phosphorus - 16.0 mm; Oxygen - 13.4 mm; Fluorine - 13.4 mm;
Holes - 2.1 mm.

Example of final constructed model see on: https://skfb.ly/oGItV

The bond lengths:
P--O - 28 mm (48 bonds);
Ca--F - 42 mm (6 bonds)
Ca-O - 46mm (12 bonds), 43 mm (12 bonds), 49 mm (6 bonds), 44 (12 bonds), 45 mm (12 bonds), and 51 mm (12 bonds).
