According to periodic properties, what would be the most likely formula for the product obtained when Lv reacts with H2 (g) ?

H₂Lv

Explanation:

Lv is at group 6 on the periodic table, so it has 6 valence electrons, likely oxygen. Thus, to be stable, it needs to gain 2 electrons. Hydrogen has 1 electron in its valence shell, so H₂ can share 2 electrons with Lv, and because of that, the product would be:

H₂Lv.
