| A polyatomic molecule with bonds which are polar is not necessarily polar itself. |
|
| The fact that a polyatomic ion has a charge means that it must have taken on or given up electrons. |
|
| The atoms in a polyatomic ion are held together by types of chemical bonds known as covalent bonds. |
|
| Atoms of two or more elements can also combine to form a polyatomic ion, a chemically distinct species with an electric charge. |
|
| In older literature, a polyatomic ion is also referred to as a radical, and less commonly, as a radical group. |
|
| Some compounds have polyatomic ions, where the ion is composed of two or more atoms. |
|
| In contrast most other nonmetals tend to form polyatomic molecules in the gaseous state. |
|
| As the name suggests, a polyatomic ion is a charged entity composed of several atoms bound together. |
|
| The sum of oxidation numbers for all atoms in a polyatomic ion equals the charge on the ion, and the sum of all oxidation numbers for atoms in a neutral molecule equals zero. |
|
| By removing the free metal ions from solution, the formation of the chloride containing polyatomic ions allows the oxidation reaction to continue toward equilibrium. |
|
| The permeability sequence follows the affinity sequence of the binding sites, and larger and polyatomic anions exhibit a higher permeability than other anions. |
|
| Molecular orbital treatment of diatomic molecules, hybridization and polyatomic molecules. |
|
| Compounds containing polyatomic ions are composed of three or more elements and usually consist of one or more cations combined with a negative polyatomic ion. |
|
| A polyatomic ion cannot exist by itself since it contains either a net positive or negative charge and thus is required to combine with other atoms to neutralize its charge. |
|
| One key issue for chemists is the nature of the vibrations in polyatomic molecules: How do the nuclei of the atoms oscillate in relation to each other? |
|
| For a polyatomic molecule such as SF6, the translation energy of the molecule now represents the half of its total energy, the other half being rotation-on-itself energy. |
|
| Fortunately, the systematic substitution of heavier isotopes at known points in polyatomic molecules gives rise to new sets of vibrational spectra that clarify the nature of the atomic motions. |
|
| The upstream materials of polyurethane include three categories, namely, isocyanates, polyatomic alcohols and auxiliaries. |
|
| The analytical method used an octopol reaction system, operated in helium and hydrogen for removal of polyatomic interferences. |
|
| Only a few representatives are given, as the number of polyatomic ions encountered in practice is very large. |
|
|
|
| The spectra are representative of many anions and polyatomic ions common to inorganic materials and are classified according to anion or polyatomic ion following groups in the periodic chart. |
|
| The chlorine-containing oxy anions provide an example: Naming ionic compounds that contain polyatomic ions is similar to naming binary ionic compounds. |
|
| Any one of these ions may be monatomic or polyatomic, however. |
|
| The determination of trace elements of average atomic mass, such as chromium, copper and nickel may be subject to strong interference from other isobaric and polyatomic ions. |
|
| In polyatomic molecules, the molecule motion can be described by a rigid body rotation and internal vibration of atoms about their equilibrium position. |
|
| Polyatomic ions can combine with oppositely charged ions, through ionic bonding. |
|
| Polyatomic ions are groups of atoms that are positively or negatively charged. |
