Here is the number of bonds each element forms:
- Chlorine (Cl): Chlorine typically forms 1 bond. This is because chlorine has 7 valence electrons and needs 1 more to complete its octet.
- Potassium (K): Potassium typically forms 1 bond. Potassium has 1 valence electron, which it tends to lose to achieve a stable electron configuration.
- Phosphate (PO₄³⁻): Phosphate forms 4 bonds. The phosphate ion has a central phosphorus atom bonded to four oxygen atoms.
- Calcium (Ca): Calcium typically forms 2 bonds. Calcium has 2 valence electrons, which it tends to lose to achieve a stable electron configuration.
