Inorganic nonmetal chlorides

Ionization is the process whereby a chemical reaction forms ions (atoms with a negative or positive charge) from the breakup of neutral molecules of some inorganic compounds. A common example is the neutral molecule of sodium chloride (NaCl, salt). When it dissociates (breaks apart) into positive metalhc ions of Na by the loss of an electron, the nonmetal chlorine ion Cl" gains the negative charge given up by the sodium atom. 

However, environmental investigations on landfill derived groundwater contamination used frequently inorganic parameters for monitoring proposes (e.g. Murray et al. 1981 Looser et al. 1999 Vilomet et al., in press). These parameters include concentration of nonmetal anionic species (chloride, nitrate, sulfate, phosphate, borate etc.), heavy metals (Ni, Cr, Fe etc.) as well as alkali and alkaline earth metals (K, Na, Mg, Ca etc.).
