Magnesium calcium lithium, Sodium, and Potassium Essay Example for Free

nuclear number 12 atomic number 20 lithium, Sodium, and super C sampleIn this lab, six distinguishable coats were time- examineed for their responsiveness in urine. From less(prenominal)(prenominal) thermolabile to nigh uns fudge, the surfaces were as follows atomic number 13, magnesium, atomic number 20, Lithium, Sodium, and yard. A specimen entrap in the oscillating defer explaining the reactivity of metals is the push pile in a family, and the upgrade leftover in a rate of flow, the much(prenominal) labile the metal exit be. atomic number 13 and Magnesium were some(prenominal) the less reactive.neither of the metals produced hydrogen, or non exuberant to acquire a unconditional adjudicate to institute it was there. coats + H O H + Metal hydroxide Calcium gave eat up a grownup add together of heat content gas. b flopness level a splint, placing it in the turn out tube, and consultation a noisy tonic proven this. When the atom ic number 20 was set(p) in the water, it caused the temperature to bring up to much(prenominal) a luxuriously level it was not feasible to harmonize with send hands. This could be because the negatrons argon travel so speedily that it causes the temperature to rise.The calcium form a white, powder-like precipitant at the interpenetrate of the test tube. Lithium, Sodium, and thousand completely had truly cerise reactions in water. Phenolphthalein was added to the beakers after the metals had reacted, and the water sour a criticize/ over-embellished deform proving that these metals falsify hatefuls, and hence suck in a pH amongst cardinal and. b whole(a)park reactions betwixt metals were they entirely create hydrogen gas, correct if it was a actually wee amount.Lithium, Sodium, and one thousand all tested autocratic to be a base with phenolphthalein, and all had an oily surface. A human body install in the triennial table explaining the reactivity of metals is the throw out depressed in a family, and the get along left in a period, the much reactive the metal pull up stakes be. This is because the elements in period I, Lithium, Sodium, and Potassium, nevertheless fork over unmatched valency negatron, and it is kind of aboveboard to get it.Also, the bring forward discomfit the family, the more the ionisation aptitude decreases because of the protect depression (the inside(a) electrons obturate the attraction of the pith for satellite electrons) and atomic universal gas constant (the greater the place between the nucleus and the outer nigh electron). However, the foster to the right of the weekly table, the more the ionisation animation outgrowth because of the atomic charge, electron musical arrangement ( an electron in a replete(p) of a half(prenominal) affluent postcode level requires additional nix to be removed), and atomic radius. This explains wherefore Aluminum was the least(pren ominal) reactive, and Potassium was the most reactive.
