• Polyatomic ions may sometimes be usefully thought of as electrically charged molecules.
• The following tables give examples of commonly encountered polyatomic ions.
• Lewis structures for polyatomic ions may be drawn by the same method.
• Ions can be metals or polyatomic ions.
• Each polyatomic ion in a compound is written individually in order to illustrate the separate groupings.
• Lorentz stated that the principle of detailed balance is not applicable to collisions of polyatomic molecules.
• Polyatomic ions are often useful in the context of hydrogen ion yields the sulfate anion ( ).
• There are two " rules " that can be used for learning the nomenclature of polyatomic anions.
• In a third research focus Rempe follows the goal to produce an ultracold gas of polyatomic molecules.
• Frank Boys was also one of the first scientists to use digital computers for calculations on polyatomic molecules.
• Anticrossings of diatomic energy curves have many similarities to the conical intersections of energy surfaces in polyatomic molecules.
• Similarly, the polyatomic nonmetals, diatomic nonmetals and the noble gases are nonmetals viewed in the broader sense.
• Only a few representatives are given, as the number of polyatomic ions encountered in practice is very large.
• Examples are the diatomic molecule hydrogen ( H 2 ) and the polyatomic molecule sulfur ( S 8 ).
• For simple ions the ionic charge and the oxidation number are identical, but for polyatomic ions they often differ.
• In the naming of inorganic compounds it is a suffix that indicates a polyatomic anion with a central tellurium atom.
• The phosphate ion is a polyatomic ion with the empirical formula and a molar mass of 94.97 g / mol.
• Note that many of the common polyatomic anions are conjugate bases of acids derived from the oxides of non-metallic elements.
• Large regions of higher density matter known as molecular clouds allow chemical reactions to occur, including the formation of organic polyatomic species.
• These polyatomic ions are groups of atoms that are covalently bound together and have an overall ionic charge, such as the sulfate ion.
