Lewis Structure:A Lewis structure is a diagram illustrating how atoms are connected within a molecule using symbols for individual elements and dots representing valence electrons.
Double Bond:In CO₂, there exists a double bond between carbon and each oxygen atom, meaning they share not just one but two pairs of electrons.
Nonpolar Molecule: CO₂ is a nonpolar molecule because the electronegativity difference between carbon and oxygen atoms is minimal, resulting in even electron distribution.
