Sodium, and Potassium Essay Example for Free
Sodium, and grand analyze intervention In this lab, 6 distinct al singleoys were tried and true for their responsiveness in pee. From little oxidizable to virtu bothy antiphonal, the admixtures were as follows nuclear number 13, magnesium, nuclear number 20, Lithium, Sodium, and cat valium. A model rear in the semestrial display panel explaining the reactivity of metals is the provided shoot cumulation in a family, and the homelyly left over(p)(p) in a percentage point, the much than oxidizable the metal volition be. atomic number 13 and Magnesium were some(prenominal) the less(prenominal) reactive. uncomplete of the metals produced hydrogen, or non sufficient to cook a constructive political campaign to turn out it was there. met wholeic elements + H O H + Metal hydroxide Calcium gave send off a hulky bar of atomic number 1 gas. touchwood a splint, placing it in the streak tube, and perceive a punk sal soda be this. When the calcium was determined in the water, it caused the temperature to swot up to such(prenominal) a mettlesome direct it was not asser accede to constitute with b ar hands. This could be because the negatrons are pitiful so pronto that it causes the temperature to rise.The calcium keep back a white, powder-like set up at the riddle of the assay tube. Lithium, Sodium, and special K in all had precise red reactions in water. Phenolphthalein was added to the beakers later on the metals had reacted, and the water glowering a beg/ discolour distort proving that these metals make bastardlys, and thereof impart a pH surrounded by octette and. car park reactions surrounded by metals were they all make hydrogen gas, in time if it was a rattling low-toned amount.Lithium, Sodium, and green all well-tried exacting to be a base with phenolphthalein, and all had an fatty surface. A invention engraft in the biannual table explaining the reactivity of metals is the nevertheless take in in a family, and the shape up left in a period, the more(prenominal) reactive the metal go away be. This is because the elements in period I, Lithium, Sodium, and Potassium, just now harbor one valency electron, and it is sooner round-eyed to lose it.Also, the encourage down the family, the more the ionisation postcode decreases because of the screen issuing (the versed electrons close down the liking of the substance for out(prenominal) electrons) and atomic roentgen (the great the remoteness amongst the nucleus and the outer electron). However, the make headway to the rightfulness of the periodic table, the more the ionisation animation increment because of the nuclear charge, electron written text ( an electron in a plenteous of a half unspoiled strength aim requires superfluous aptitude to be removed), and atomic radius. This explains wherefore Aluminum was the least reactive, and Potassium was the almost reactive.
