List of Tables:

The tables below list usual polyatomic ions that you will certainly be usingthroughout this General-tastecraftedmcd.com laboratory series (Chem 151-152). These ion areseparated by fee on the ion into four (4) different tables and provided alphabeticallywithin each table. For each polyatomic ion, the name, tastecraftedmcd.com formula, two-dimensionaldrawing, and three-dimensional depiction are given.

The three-dimensional structures are drawn as CPK models. CPK structuresrepresent the atoms together spheres, where the radius of the ball is same to the valve derWaals radius that the atom; this structures give an almost right volume that the polyatomicion. In these tables, the three-dimensional structures have actually all been attracted to the samescale; because of this you have the right to compare their loved one sizes. In addition, the atom in the CPKstructures have been color-coded to complement the two-dimensional illustrations for easiercomparison.

To watch the ion interactively, please use RASMOL,a computer system application i m sorry is easily accessible for both Macs and also PCs and also can be downloaded atthe RASMOL site. Come download the pdb papers (refers come the protein databank technique ofsaving atomic coordinates for a molecule) for viewing and also rotating the ions provided in thetables below, please click the proper three-dimensional structure.


You are watching: Which of the following polyatomic ions has a positive charge

(Note: If youwant to see multiple link simultaneously, you re welcome download each pdb paper and conserve onyour computer. Then open RASMOL outside of Netscape.) NOTE: CPK sizes for metalatoms Cr and Mn will be untrue in RASMOL.
