• D.

Answer: (B)

Verified step by step guidance

1. Identify the element: Cobalt (Co) is a transition metal with atomic number 27.
2. Determine the electron configuration: The electron configuration of neutral cobalt is [Ar] 3d^7 4s^2.
3. Account for the ion charge: Co^+ indicates that cobalt has lost one electron, typically from the outermost s orbital, resulting in [Ar] 3d^7 4s^1.
4. Draw the Lewis Dot symbol: Transition metals like cobalt do not typically follow the octet rule, but for simplicity, you can represent the remaining valence electron from the 4s orbital as a single dot around the Co symbol.
5. Consider the charge: Enclose the Lewis Dot structure in brackets and indicate the positive charge outside the brackets to represent the ion.
