Covalent Bonding Worksheet #1: Bond Formulas Guide: We humans are loaded with covalently bonded molecules. How are these molecules bonded together? To find the number of bonds in an element, use the number of valence electrons to draw the electron dot structure. Paired electrons form non-bonding lone pairs of electrons, and unpaired electrons each form a bond. 1. Complete the table below to help guide you in bond formations below. A few are done to assist you: Element Valence electrons Lone pairs Bonds H 1 0 1 P 5 1 3 Cl O Si 2. Use this information to draw the molecules, including bonds and lone pairs of electrons.
