The image depicts the Lewis structure of the cyanate ion, represented as \([ \text{O} \equiv \text{C} \equiv \text{N} ]^-\).

### Description:

- **Atoms and Bonds:**
  - The structure consists of three atoms: Oxygen (O), Carbon (C), and Nitrogen (N).
  - Oxygen is single-bonded to Carbon.
  - Carbon is triple-bonded to Nitrogen.

- **Lone Pairs:**
  - The Oxygen atom has six valence electrons, represented by three lone pairs (depicted as pairs of dots around the O).
  - The Nitrogen atom has two lone pairs, each represented by two dots.

- **Charge:**
  - The entire structure is enclosed in square brackets with a negative charge (\(^-\)), indicating that the cyanate ion carries an overall negative charge.

### Explanation:
The cyanate ion is an anion with the formula \(\text{OCN}^-\). The structure indicates resonance and the formal charges are typically distributed over the atoms, although the structure shown presents a commonly used representation.

This diagram is often used to teach concepts of resonance, formal charge, and the representation of ions in chemistry.
