Re: Seesaw Shape

There are 5 regions of electrom density creating a trigonal bipyramidal e- arrangement. Since one region of e- density is a lone pair the result after the spacing out of the atoms and condensing of angles is a seesaw.

Re: pi and sigma bonds

In terms of hybridization pi bonds (more than a single bond) would imply that there are other orbitals besides the hybridized orbital.

Re: Bonds between 1.5 and 2 [ENDORSED]

The closer the distance between the electronegativities is to 2 then the bond has more ionic character. The closer the distance between the electronegativities is to 1.5, the bond has more covalent character.

Re: Octet rule

Elements from the 3rd period and below can break the octet rule and acquire more than 8 valence electrons (an octet) due to the presence of the d orbital.
