The oxidation number of sodium (Na) in sodium chloride (NaCl) is +1. This is because sodium typically loses one electron to achieve a stable electron configuration, resulting in a positive charge.

Understanding Oxidation Numbers

Oxidation numbers indicate the degree of oxidation of an atom in a compound. Here’s a quick breakdown:

  • Na in NaCl: +1
  • Cl in NaCl: -1

Why +1 for Sodium?

Sodium is an alkali metal found in Group 1 of the periodic table. It readily loses one electron, which is why its oxidation state in compounds like NaCl is +1.

Thus, the correct answer is C) +1.
