The scenario describes a molecule where two atoms of the same element share six electrons. Sharing six electrons indicates a triple bond, which is characteristic of nitrogen.
Among the options given:
- O₂ (oxygen) has a double bond, sharing four electrons.
- N₂ (nitrogen) has a triple bond, sharing six electrons.
- F₂ (fluorine) has a single bond, sharing two electrons.
- Si₂ (silicon) typically forms single bonds with four electrons, not applicable for a triple bond.
Thus, the molecule that could be the product of the reaction is N₂.
