2. VSEPR theory - Wikipedia

   en.wikipedia.org/wiki/VSEPR_theory

   VSEPR theory is used to predict the arrangement of electron pairs around central atoms in molecules, especially simple and symmetric molecules. A central atom is defined in this theory as an atom which is bonded to two or more other atoms, while a terminal atom is bonded to only one other atom.

3. Wikipedia : Graphics Lab/Resources/PDF conversion to SVG

   Click that key, and then open an image editor and click "paste" (usually in the edit menu). Finally, Wikipedia:Graphic Lab/Image workshop can create, extract, or edit almost any image. Just leave a request for help or advice there. Now here is some info on how to convert PDF image to SVG images. This page covers conversion using free tools.

4. Bent molecular geometry - Wikipedia

   en.wikipedia.org/wiki/Bent_molecular_geometry

   This geometry is almost always consistent with VSEPR theory, which usually explains non-collinearity of atoms with a presence of lone pairs. There are several variants of bending, where the most common is AX 2 E 2 where two covalent bonds and two lone pairs of the central atom (A) form a complete 8-electron shell .

5. Trigonal pyramidal molecular geometry - Wikipedia

   en.wikipedia.org/wiki/Trigonal_pyramidal...

   In chemistry, a trigonal pyramid is a molecular geometry with one atom at the apex and three atoms at the corners of a trigonal base, resembling a tetrahedron (not to be confused with the tetrahedral geometry).
