Unformatted text preview: Soil Solution Constituents Many of the most prominent constituents In soils are dissolved ions. What is an Ion? Elements Electrons (-) Protons (+) Elements in the periodic table have equal numbers of protons (+) and electrons (-). They are electrically neutral Ions: Losing Electrons Ions are stable forms of elements that acquire an electrical charge by gaining or losing electrons Elemental Sodium (Na) 11 protons (+), 11 electrons (-) Sodium ion (Na + ) 11 protons (+), 10 electrons (-) By losing an electron, sodium has more protons than electrons and becomes positively charged. Na - 1e- = Na + Na 11 protons e- e- e- e- e- e- e- e- e- e- e- + Na + Sodium Na 2Na + 2H 2 2Na + + 2 OH- + H 2 http://video.google.com/videoplay?docid=-2158222101210607510&ei=syO5SuaVBJLiqgKWif37AQ&q=sodium+explosion&hl=en# e Ions: Gaining Electrons Ions are stable forms of elements that acquire an electrical charge by gaining or losing electrons Elemental Chlorine (Cl) 17 protons (+), 17 electrons (-) Chloride ion (Cl...
