Why does the s-block portion of the periodic table span two groups?

Using data from seismic waves, geologists have learned that earth’s interior is made up of several

Consider this initial-rate data at a certain temperature for the reaction described by

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.
