What happens when sodium reacts with chlorine?
Sodium and chlorine form sodium chloride, an ionic solid. The balanced equation is 2Na(s) + Cl₂(g) → 2NaCl(s).

Balanced reaction
2Na(s) + Cl₂(g) → 2NaCl(s)
Two sodium atoms are needed for one chlorine molecule because elemental chlorine is written as Cl₂.

-
01
Start with the reactants
The reactant side contains sodium metal, Na, and diatomic chlorine gas, Cl₂.
-
02
Track the electron transfer
Each sodium atom loses one electron and each chlorine atom gains one, producing Na⁺ and Cl⁻ ions.
-
03
Name the product
Oppositely charged ions attract in a crystal lattice, so the product is solid sodium chloride, NaCl.

What to notice in OmniLab
- The prepared setup selects Sodium and Chlorine.
- The prediction uses those selected chemicals only.
- The beaker is a visual aid and does not change the prediction.
