Prove the Correct Order of Reactivity of Metals :: Metal Reactivity Science Experiments Essays

go up the Correct Order of Reactivity of MetalsAimThe aim of this experiment is to decree a method of mathematic solelyyanalysing the order of metallic element reactivity. This involved finding a safe,dependant variable which is numerically measurable. After testing allthe metals and measuring such a variable, is my hope to set all of themetals into a proven, accurate order of activity.PlanEvery fixings of the periodic dishearten is made up of touchs. Each of theatoms consists of subatomic particles which mark up a nucleus andouter(a) orbits. The nucleus contains positively charged protons, andneutrally charged neutrons. These make up the relative mass of theatom. Orbiting the nucleus, attracted by the positive charge of theprotons, ar the electrons. This are arranged in layers, called nixlevels, and necessitate no mass. moreover a certain flesh of electrons fit oneach sinew level, and it is this which affects the reactivity ofcertain materials and is also the way that t he periodic table isarranged.The number of electrons in the outer energy level is the groupin which the element is placed. The first level (nearest the nucleus)will only hold 2 electrons, the act holds 8, and the third alsoseems to be full when it has 8 electrons.If all of the energy levels in the atom are full populated withelectrons, it is said to be stable, and in most cases, is whereforeunreactive. Examples of this include the noble (or inert) gases suchas neon or argon. However if the outer energy level of the atom is notstable, it will automatically try to either pee or lose electrons tobecome stable. This is achieved by an ionic reaction. Ionic bondingoccurs when the outer atoms of on material changes orbit and joinsanother material for example sodium chlorideAs you can see, sodium is a group one metal (it has one electron onits outer energy level) so is therefore unstable. Chlorine on theother hand is a group 7 element. It is much easier for sodium to loseits outer electr on to become stable, than it is for it to gain 7. Thesame is true for the chlorine gaining 1 as opposed to losing seven. whence the outer electron of the sodium switches orbits to thechlorine. This creates a Na+ ion and a Cl- ion. Because oppositesattract, it intend that the two substances create an ionic bond andform sodium chloride classify one metals are the most reactive as they only have one, easilyremoved, electron. However if you view the periodic table
