What is the difference between trigonal pyramidal molecular shape vs. trigonal planar molecular shape? Why does the bond angle change between these molecular shapes when they both
include 3 attached atoms?

What is the temperature of one mole of helium gas at stp?

An atom of which element reacts with an atom of hydrogen to form a bond with the greatest degree of polarity ?

According to the valence shell electron pair repulsion (vsepr) theory, a molecule that has four electron groups around the central atom will exhibit what electron geometry? view available hint(s) according to the valence shell electron pair repulsion (vsepr) theory, a molecule that has four electron groups around the central atom will exhibit what electron geometry? trigonal bipyramidal tetrahedral square planar determination of electron geometry requires information on whether the electron groups are lone pairs or bonding groups.
