Answer

Explanation:

Step1: Analyze the chemical equation

The equation $Na^{+}+Cl^{-}\rightarrow NaCl$ shows a 1:1:1 ratio of sodium ions ($Na^{+}$), chloride ions ($Cl^{-}$) and formula - units of sodium chloride ($NaCl$).

Step2: Evaluate each option

  • Option 1: Since 1 sodium ion combines with 1 chloride ion to form 1 formula - unit of salt ($NaCl$), the number of sodium ions is equal to the number of formula units of salt. This is correct.
  • Option 2: In the reaction, the ratio of sodium ions to chloride ions is 1:1, so the number of sodium ions is not less than the number of chloride ions. This is incorrect.
  • Option 3: The ratio of chloride ions to formula units of salt is 1:1, so the number of chloride ions is not less than the number of formula units of salt. This is incorrect.
  • Option 4: The ratio of sodium ions to formula units of salt is 1:1, not 2:1. This is incorrect.

Answer:

The number of sodium ions is equal to the number of formula units of salt.
