Using the Lewis structure of H2 hydrogen gas, O2 oxygen gas, and N2 nitrogen gas determine which one contains a single bond? Which one contains a double bond? Which one contains a triple bond?

Question

Using the Lewis structure of H2 hydrogen gas, O2 oxygen gas, and N2 nitrogen gas determine which one contains a single bond? Which one contains a double bond? Which one contains a triple bond?

Answer 1

H₂ contains a single bond.

O₂ contains a double bond.

N₂ contains a triple bond.

H₂ has 2 valence electrons H:H single bond

O₂ has 12 valence electrons O::O double bond with 2 lone pairs on each oxygen

N₂ has 10 valence electrons N≡N triple bond with 1 lone pair on each nitrogen
