This statement is false. The Lewis dot structure for oxygen gas (O2) actually contains a double bond, not a triple bond.
To explain further, each oxygen atom has six valence electrons. When two oxygen atoms bond together, they share four electrons—two pairs—which forms a double bond. In a Lewis structure, this is represented by two lines connecting the two oxygen atoms.
A triple bond would imply that there are three pairs of shared electrons (or six electrons total shared), which is not the case for molecular oxygen. Therefore, the correct Lewis structure shows a double bond between the two oxygen atoms, confirming that the initial statement is false.
