Solution

Understanding the Sodium Ion

A sodium ion, represented as Na⁺, is a positively charged ion (cation). This nomenclature is crucial for understanding the ion's properties and behavior in chemical reactions.

Explanation of Charge

  1. Definition of Charge: Ions are atoms or molecules that have gained or lost one or more electrons, resulting in a net positive or negative charge.
  2. Sodium Atom Behavior: Sodium (Na) is an alkali metal with an atomic number of 11, meaning it has 11 protons and, in its neutral state, also 11 electrons. To achieve a stable electron configuration, sodium tends to lose one electron.
  3. Formation of Na⁺: When sodium loses an electron, it results in one more proton than electrons, leading to an overall positive charge.

Final Answer

The overall charge of a sodium ion (Na⁺) is +1.
