The molecular geometry, or three-dimensional shape of a molecule or polyatomic ion, can be determined using valence-shell electron-pair repulsion (abbreviated VSEPR and pronounced “VES-per”) theory, in which the basic principle is valence electrons around a central atom stay as far apart as possible to minimize the repulsions.

A new germanium(II) phosphate, sodium tetragermanium tris(phosphate), Na[Ge 4 (PO 4) 3], has been synthesized by a solid-state reaction. The compound is isotypic with A[Sn 4 (PO 4) 3](A = Na, K, NH 4). It features a [Ge 4 (PO 4) 3] framework made up of GeO 3 pyramids and PO 4 tetrahedra, which are linked by shared corners, yielding a three ...
Determine the Lewis dot structure of the compound. Determine the Electron geometry from the Lewis dot structure. Determine the molecular geometry. It is very important from the onset that students understand the difference between electronic geometry and molecular geometry.
7.1 Ionic Bonding. By the end of this section, you will be able to: Explain the formation of cations, anions, and ionic compounds. Predict the charge of common metallic and nonmetallic elements, and write their electron configurations. As you have learned, ions are atoms or molecules bearing an electrical charge.

12 sie 2024 · VSEPR makes a distinction between electron group geometry, which expresses how electron groups (bonds and nonbonding electron pairs) are arranged, and molecular geometry, which expresses how the atoms in a molecule are arranged. However, the two geometries are related.
