Pure hydrogen peroxide, $\mathrm{H}_{2} \mathrm{O}_{2}(l)$, is a colorless liquid that is caustic to the skin, but a $3 \%$ aqueous solution is a mild bleaching agent. Write the Lewis formula for a $\mathrm{H}_{2} \mathrm{O}_{2}$ molecule.

Key Concepts

Valence Electrons

Valence electrons are the electrons in the outermost shell of an atom that participate in bonding. When drawing a Lewis structure, the total number of valence electrons is determined by summing those from each atom, which then guides the placement of bonds and lone pairs to satisfy the octet rule.

Formal Charge and the Octet Rule

Formal charge calculations are used to ensure that the most stable arrangement of electrons is chosen for the molecule. When constructing Lewis structures, one must assign electrons to atoms in a way that minimizes overall formal charges while also allowing atoms (especially main-group elements) to complete an octet, contributing to the stability of the molecule.

Lewis Structures

Lewis structures are diagrams that represent the arrangement of electrons in a molecule. They show how atoms share electrons through bonds and display the lone pairs of electrons around atoms. This approach helps predict molecular shape, reactivity, and the fulfillment of the octet rule.
