What is the bond angles in a Tetrahedral shape? 109.5
What is the shape called with a 107 bond angle? Pyramidal
What is the bond angle in a Trigonal Bipyramidal Shape? 120 + 90
What is the bond angle in a Non-linear shape? 104.5
How many lone pairs of electrons are in a Pyramidal Shape? 1
How many lone pairs of electrons are in a Non Linear shape? 2
By how much does a lone pair of electrons reduce the bond angle by? 2.5
