Question

Sodium chloride is an ionic compound. The reaction below shows how sodium chloride forms from sodium and chlorine. Which statements describe this reaction? Check all that apply.         2Na(s) + Cl2(g) → 2NaCl(s)
   Each sodium atom loses one electron.
 Each chlorine atom loses one electron.
  Each chlorine atom gains two electrons.
The charge of the sodium ion in NaCl is +2.
  The charge of the chloride ion in NaCl is -1.

Answer 1

Answers are:

1) Each sodium atom loses one electron.

2) The charge of the chloride ion in NaCl is -1.

Oxidation reaction: Na⁰ → Na⁺¹ + e⁻ /×2; 2Na⁰ → 2Na⁺¹ + 2e⁻.

Reduction reaction: Cl₂⁰ + 2e⁻ → 2Cl⁻.

Sodium change lose electrons and change oxidation number from 0 to +1 (oxidation). Chlorine change oxidation number from 0 to -1 (reduction reaction).
