Elemental magnesium consists of three isotopes: 24mg with an accurate mass of 23.99 amu, 25mg with an accurate mass of 24.99 amu, and 26mg with an accurate mass of 25.99 amu. if 24mg is 79% of naturally occurring magnesium, what is the percent abundance of 26mg?

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.
