File Name: cations and anions list .zip
All natural waters contain, in various concentrations, dissolved salts which dissociate in water to form charged ions. Positively charged ions are called cations; negatively charged ions are called anions. Ionic impurities can seriously affect the reliability and operating efficiency of a boiler or process system.

Cations and anions are the two types of ions. Ions have an imbalance of electrical charge, meaning they contain different numbers of protons and electrons. Cation have a positive electrical charge and have more protons than electrons. Anions have a negative electrical charge and have more electrons than protons. Neutrons are electrically neutral, so their number determines the isotope , but has no effect on whether a chemical species is an ion.
The method is a short cut to correct formula writing as long as we remember to simplify our subscripts. Math Activities. Polyatomic Ions File Type nomenclature worksheet 3 ionic compounds containing polyatomic ions file type and collections to check out. In order to write formulas for polyatomic ions, you have to look at a chart or table of polyatomic ions to find out what the charge of each one is. Polyatomic ions worksheet answer key.
The charge of the electron is considered negative by convention. The negative charge of an ion is equal and opposite to charged proton s considered positive by convention. The net charge of an ion is non-zero due to its total number of electrons being unequal to its total number of protons. A cation is a positively charged ion with fewer electrons than protons while an anion is negatively charged with more electrons than protons, because of their opposite electric charges; cations and anions attract each other and readily form ionic compounds. Ions consisting of only a single atom are termed atomic or monatomic ions , while two or more atoms form molecular ions or polyatomic ions.

Accurate quantification of cations and anions remains a major diagnostic tool in understanding diseased states. Specifically, cations and anions were measured in liquid samples: serum, urine, and cerebrospinal fluid, as well as tissue samples: liver, cortex, hypothalamus, and amygdala.
