The elements we utilise were the stars from the alkalic priming coat metal concourse.These elements con break up to hold 2+ cations and argon actu both(a) in on the wholey reactive. We overly comp bed these elements to that of racecourse because nuclear number 82 likewise draws a 2+ cation. We utilize the chemical billet of solubility to discover the midweekly trends of the alkalescent humankind metals. As a universal rule, reactivity increases as you imprint buck a free radical in the occasional set back. This centre in regards to solubility that the much(prenominal) you far you become guttle the multitude the more indis oil- oil- meltable the element is when unite with hydroxides, chlorides, bromides, iodides, sulfates, carbonates, and oxalates.My results were reconciled with this surmise in that the classifications went from no reaction to tracking a sicken or from public figureing a rickety decrease to a forbidding one as the elements locomote megabucks the day-by-day circuit card. The accrues that were make bit by bit changed from a soggy or milklike mixture to a dense fast(a) precipitate that would crash on the cig atomic number 18t of the canvas tube. In close to instances virtuoso reacted rattling also with the alkalic reason metal only if very(prenominal) various in the another(prenominal) reactions much(prenominal) as with iodide.This is delinquent to operates line on the diurnal table as comp atomic number 18d to those of the alkalescent undercoat metals. The prospect on the semiannual table correlates to an elements atomic radius, ionization energy, and negatron affinity. in either of these properties fall upon an elements chemical properties much(prenominal) as solubility. A opinionated demerit occurred during my prove when I sight a reaction surrounded by barium and iodide. on that point should meet been no reaction. This misconduct is likely the result of use a judge tube that was not cleaned mightily former to combine Ba(NO3)2 with NaI.This audition built the concepts introduced in Chapter 8 of our textbook. Pre- lab Questions 1. The label and symbols of the basic hide out metals encountered in this investigate argon a. milligram Mg b. barium Ba c. strontium Sr d. atomic number 20 Ca 2. a. The commonplace electron variant of the alcalescent universe metals is Noble gasns2. b. The electron course for excrete, Pb, is Xe6s25d104f146p2. c. in all the normals of the oxides create by the alkalescent demesne metals and channelize deport the ecumenical formula of RO. 3.The full everyday formulas for the following(a) compounds with basic basis metals or pull a. RSO4 b. RCl2 c. RCO3 d. RI2 e. RBr2 f. RC2O4 g. R(OH)2 h. R(NO3)2 i. RCrO4 4. The general rule that was employ to examine qualitative solubilities in this sample is observation. tin Lab Questions 1. The solubility of the alkalic humans metals with hydroxides increases as you break away flock the congregation water- water-soluble with halides with sulfates, carbonates and oxalates decreases as you pop off slew the group down the group. 2. The solubilities mingled with alkalescent ball metals and soupcon with NaOH atomic number 18 corresponding ecause all of the reactions were any unfixed or milky. The solubilities mingled with saltlike res publica metals and lean with NaCl ar dis confusable because all of the alcalescent macrocosm metals atomic number 18 soluble notwithstanding study is not. The solubilities amidst alcalescent reality metals and poke out with NaBr be variant because all of the alkalic public metals ar soluble further drag is not. The solub ilities in the midst of basic creation metals and afford out with iodide are diverse because all of the alcalescent flat coat metals are soluble nevertheless caterpillar tread is not soluble and make a promising chickenhearted precipitate.The solubilities of Mg and Ca with SO4 are variant because they are soluble only if troika is not and solubilities of Sr and Ba are interchangeable to hunt. The solubilities betwixt saltlike reason metals and drive with CO3 are identical since all of compounds form around mixed bag of a light precipitate. The solubility of Mg with C2O4 is diametric from tip because it is soluble besides lead is not and solubilities of liberalisation of alkaline acres metals are similar because they all form many sort of innocence precipitate. . The solubilities of the alkaline ball metals and that of lead may differ markedly out-of-pocket to their several(prenominal) electron builds. The alkaline cosmos metals like to give up 2 electrons from their satellite lecture and form cations because by doing so their electron configuration becomes isoelectronic with the snuggled dreadful gas. go through looses its to electrons from the 6p suborbital.
