Abbreviation for valence-shell electron-pair repulsion theoryA means of predicting the structures of simple ions and molecules, or of individual atoms in more complex molecules or ions, by counting the number of pairs of electrons in the valence shell of a central atom.; a means of predicting the structures of simple ions and molecules, and single atomsThe smallest particle of an element that can be involved in chemical combination with another element; an atom consists of protons and neutrons in a tiny, very dense nucleus, surrounded by electrons, which occupy most of its volume. in more complexA central metal and the ligands surrounding it; also called coordination complex. molecules or ions, by counting the number of pairs of electrons in the valence shell of a central atomIn a small molecule or ion, the atom to which the other atoms are bonded. The central atom is surrounded by the other atoms..
