WebStep 1. We divide the bonding electron pairs equally for all I–Cl bonds: Step 2. We assign lone pairs of electrons to their atoms. Each Cl atom now has seven electrons assigned to it, and the I atom has eight. Step 3. Subtract this number from the number of valence electrons for the neutral atom: I: 7 – 8 = –1. WebKinds of Solids —crystalline solids vs. amorphous solids-crystalline solids have long range order; amorphous solids do not have long range order Crystalline Solids are ionic, molecular, covalent network, or metallic examples: ionic —e.g., NaCl; built from attraction of cations with anions molecular —e.g., sucrose; discrete molecules held together by intermolecular …
