In the present compendium, spectra of inorganic compounds in the solid phase are presented. They are considered to be ONE unit and act as single ions. Show how these ions combine to make a compound. answers These ions are polyatomic ions. ; Each polyatomic ion in a compound is written individually in order to illustrate the separate groupings. For example, the polyatomic ion sulfate (SO 4 2-), needs two electrons to ensure that each atom that makes up the polyatomic ion will reach a stable state. Together , they carry a charge N O O O 1 – 9. ScienceStruck lists down some common polyatomic ions with their charges and oxidation numbers. The electrical charge of this ion is a result of the number of electrons present in each atom; if there are more electrons than the total number of protons in atoms, it gets a net negative charge and vice versa. Often, these ions are charged and combine with metals to form ionic bonds. Thus, a polyatomic ion is an ion that is composed of 2 or more atoms. Example – Na +, Cl –, O-2, Al +3, N-3 (nitride), Mg +2, Ca +2, Cu +2, Fe +2 etc. In case the cation has a Roman number after that, that is the charge in that cation.
