Lewis Dot Structures describe the connectivity of the atoms in a species. a) Determine the central atom (least electronegative) Hydrogen will not be a central atom. b) Draw the skeleton. c) Determine the total number of valence shell electrons d) Place the electrons around the terminal atoms to satisfy the octet rule (Be). Hydrogen ok with two electrons. If there are electrons left over then place them around the central atoms as lone pair electrons. Some atoms (period 3 and...
