Document Summary

10. 1 depicting molecules and ions with lewis structures. Lewis structure shows electron-dot symbols for the atoms, the bonding pairs as lines, and the lone pairs that fill each atom"s valence shell as pairs of dots. Applying the octet rule: the octet rule: each atom fills its outer level with eight electrons (or two for hydrogen, molecules with single bonds, place the atoms relative to each other. Place the atom with the lower group number in the center because it needs more electrons to attain an octet; usually with the lower electronegativity. If the atoms have the same group number, place the atom with the higher period number (also lower en) in the center: determine the total number of valence electrons. For molecules, add up the valence electrons of the atoms: draw a single bond form each surrounding atom to the central atom and subtract.
