The word equation for calcium plus chlorine equals chloride is incorrect. Here's why:

* Chlorine exists as a diatomic molecule: Chlorine gas is found in nature as Cl₂, not as individual chlorine atoms.

* The product is calcium chloride: When calcium (Ca) reacts with chlorine (Cl₂), the product formed is calcium chloride (CaCl₂).

Here's the correct word equation:

Calcium + Chlorine → Calcium Chloride

And the balanced chemical equation:

Ca + Cl₂ → CaCl₂
