In the field of chemistry, one type of chemical is seen by many as something that nobody ever wants to be in a room with: hydrofluoric acid, HF. Only a handful of
chemists in the world utilize HF to perform specific experiments in regards to fluorine
centered chemistry. This fear stems from the scenario of hydrofluoric acid coming in
contact with calcium found in bones. The process in which this occurs is shown in the
balanced chemical equation below:
Ca3(PO4)2 (s) + 6 HF(aq) → 3 CaF2(aq)→ 3 CaF2 (aq) + 2 H3PO4 (aq)
Using your knowledge of periodic trends and ionic activity, create a CER
(Claim - Evidence - Reasoning) why fluorine would rather bind to calcium than
hydrogen as posed in the balance chemical equation above. You must include at
least two pieces of evidence from the periodic table, your scientific notebook, or other
