To represent the Lewis Dot structure for sodium chloride (NaCl), we need to show how sodium (Na) donates its one valence electron to chlorine (Cl), which has seven valence electrons. Here’s how it breaks down:
- Sodium (Na) has one valence electron and becomes a positive ion (Na⁺) after losing that electron.
- Chlorine (Cl) has seven valence electrons and becomes a negative ion (Cl⁻) after gaining one electron.
Therefore, the correct option should represent:
- Na as a positive ion
- Cl as a negative ion
- Na should have no dots (indicating it has lost its electron)
- Cl should have eight dots around it (indicating it has completed its octet).
Based on your options, the most fitting representation would be:
C: N, a, one positive, C, l, one negative
This choice communicates that Na is positive and Cl is negative.
- Sodium (Na) has one valence electron and becomes a positive ion (Na⁺) after losing that electron.
- Chlorine (Cl) has seven valence electrons and becomes a negative ion (Cl⁻) after gaining one electron.
Therefore, the correct option should represent:

- Cl as a negative ion
- Na should have no dots (indicating it has lost its electron)
- Cl should have eight dots around it (indicating it has completed its octet).
