Plz me valence shell electron pair repulsion or vsepr theory states that the geometry of a molecule or polyatomic ion is determined by the repulsion of pairs of electrons associated with a central atom. the pairs of electrons may be bonding or non-bonding (lone-pair) electrons. only valence electrons of the central atom influence the molecular shape. all but one assumption listed supports vsepr theory. which statement is not critical to supporting vsepr theory? a) opposite charges attract. b) atoms of elements contain equal numbers of protons and electrons. c) pairs of negative electrons in the valence shell of a central atom repel each other. d) pairs of electrons tend to occupy positions that minimize repulsions and maximize the distance between them. plz 'm soo confused
