Magnesium has three naturally occurring isotopes (mg-24, mg-25, and mg-26). the atomic mass and natural abundance of mg-24 are 23.9850 amu and 79 %, respectively. the atomic mass and natural abundance of mg-25 are 24.9858 amu and 10 %, respectively. find the natural abundance of mg-26.

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.
