number of valence electrons in each atom.

Explanation: Lewis structures represent how valence electrons are shared or paired to form bonds and lone pairs. Knowing valence electrons lets you count the total electrons, place bonds, complete octets (or exceptions), and assign formal charges. Bond length, ionization energy, and atomic mass are not needed to draw a basic Lewis structure.
