Final answer:
Ca3(PO4)2 makes an ionic bond, where calcium ions (Ca2+) and phosphate ions (PO43-) are held together in a lattice structure by electrostatic forces.
Step-by-step explanation:
The compound Ca3(PO4)2 consists of calcium ions (Ca2+) and phosphate ions (PO43-). In this compound, the calcium ions and phosphate ions form an ionic bond, which occurs when a metal and a non-metal exchange electrons, leading to a compound consisting of positively and negatively charged ions held together by electrostatic forces.
The calcium ion, with a charge of 2+, will bond with the phosphate ion, which has a charge of 3-, forming a stable ionic lattice structure.
