What does the double line, which looks much like an equals sign, represent in Lewis structures?

A) A 2-electron single bond
B) A 4-electron double bond
C) A 2-electron double bond
D) A 4-electron single bond

Lewis Structures

Lewis structures are diagrams that represent the valence electrons of atoms within a molecule, indicating the bonds between atoms and the lone pairs of electrons.

Double Line

In chemistry, it often represents a double bond between atoms, indicating that two pairs of electrons are shared in the bond.

Electron

A subatomic particle with a negative electrical charge, found in all atoms and acting as the primary carrier of electricity in solids.
