Explanation:

Step1: Recall Group 1 valence electrons

Group 1 elements (alkali metals) have 1 valence electron.

Step2: Analyze Lewis dot structures

Lewis dot structures show valence electrons. A Group 1 element will have 1 dot (electron) around the symbol \( X \). The first option \( X^\bullet \) (or \( X \cdot \)) has 1 dot, matching the 1 valence electron of Group 1. The other options have more dots (2, 5, 7 valence electrons - incorrect for Group 1).

Answer:

\( X^\bullet \) (the first option with one dot around \( X \))
