= = Reactivity Lab 11th. Dec. 2009 · Aim: To rank the reactivity of 5 metals which are iron, aluminum, copper, magnesium, zinc · Variables:  1. Iron 2. Aluminum 3. Copper 4. Magnesium 5. Zinc In the hydrochloric acid. || · Hypothesis: ‘IF’ we put different type of metal, ‘THEN’ the element located closer to the noble gases and located in the high energy period will be more reactive, ‘BECAUSE’ the electrons can move away or get into the valent shell quickly if they are further away from the nucleus or they only need to gain or lose small number of electrons which makes the substance more reactive. · Equipment and Materials:  -  5 test tubs <span style="color: #7030a0; font-size: 16pt; line-height: 115%; mso-ascii-font-family: Calibri; mso-bidi-font-family: Calibri; mso-fareast-font-family: Calibri; mso-hansi-font-family: Calibri; msoasciifontfamily: Calibri; msobidifontfamily: Calibri; msofareastfontfamily: Calibri; msohansifontfamily: Calibri; msolist: Ignore;"> -  A rack <span style="color: #7030a0; font-size: 16pt; line-height: 115%; mso-ascii-font-family: Calibri; mso-bidi-font-family: Calibri; mso-fareast-font-family: Calibri; mso-hansi-font-family: Calibri; msoasciifontfamily: Calibri; msobidifontfamily: Calibri; msofareastfontfamily: Calibri; msohansifontfamily: Calibri; msolist: Ignore;"> -  A scale <span style="color: #7030a0; font-size: 16pt; line-height: 115%; mso-ascii-font-family: Calibri; mso-bidi-font-family: Calibri; mso-fareast-font-family: Calibri; mso-hansi-font-family: Calibri; msoasciifontfamily: Calibri; msobidifontfamily: Calibri; msofareastfontfamily: Calibri; msohansifontfamily: Calibri; msolist: Ignore;"> -  A cylinder <span style="color: #7030a0; font-size: 16pt; line-height: 115%; mso-ascii-font-family: Calibri; mso-bidi-font-family: Calibri; mso-fareast-font-family: Calibri; mso-hansi-font-family: Calibri; msoasciifontfamily: Calibri; msobidifontfamily: Calibri; msofareastfontfamily: Calibri; msohansifontfamily: Calibri; msolist: Ignore;"> -  0.5g of Iron <span style="color: #7030a0; font-size: 16pt; line-height: 115%; mso-ascii-font-family: Calibri; mso-bidi-font-family: Calibri; mso-fareast-font-family: Calibri; mso-hansi-font-family: Calibri; msoasciifontfamily: Calibri; msobidifontfamily: Calibri; msofareastfontfamily: Calibri; msohansifontfamily: Calibri; msolist: Ignore;"> -  O.5g of Aluminum <span style="color: #7030a0; font-size: 16pt; line-height: 115%; mso-ascii-font-family: Calibri; mso-bidi-font-family: Calibri; mso-fareast-font-family: Calibri; mso-hansi-font-family: Calibri; msoasciifontfamily: Calibri; msobidifontfamily: Calibri; msofareastfontfamily: Calibri; msohansifontfamily: Calibri; msolist: Ignore;"> -  0.5g of Copper <span style="color: #7030a0; font-size: 16pt; line-height: 115%; mso-ascii-font-family: Calibri; mso-bidi-font-family: Calibri; mso-fareast-font-family: Calibri; mso-hansi-font-family: Calibri; msoasciifontfamily: Calibri; msobidifontfamily: Calibri; msofareastfontfamily: Calibri; msohansifontfamily: Calibri; msolist: Ignore;"> -  0.5g of Magnesium <span style="color: #7030a0; font-size: 16pt; line-height: 115%; mso-ascii-font-family: Calibri; mso-bidi-font-family: Calibri; mso-fareast-font-family: Calibri; mso-hansi-font-family: Calibri; msoasciifontfamily: Calibri; msobidifontfamily: Calibri; msofareastfontfamily: Calibri; msohansifontfamily: Calibri; msolist: Ignore;"> -  0.5g of Zinc <span style="color: #7030a0; font-size: 16pt; line-height: 115%; mso-ascii-font-family: Calibri; mso-bidi-font-family: Calibri; mso-fareast-font-family: Calibri; mso-hansi-font-family: Calibri; msoasciifontfamily: Calibri; msobidifontfamily: Calibri; msofareastfontfamily: Calibri; msohansifontfamily: Calibri; msolist: Ignore;"> -  40ml of Hydrochloric acid <span style="color: #7030a0; font-size: 16pt; line-height: 115%; mso-ascii-font-family: Calibri; mso-bidi-font-family: Calibri; mso-fareast-font-family: Calibri; mso-hansi-font-family: Calibri; msoasciifontfamily: Calibri; msobidifontfamily: Calibri; msofareastfontfamily: Calibri; msohansifontfamily: Calibri; msolist: Ignore;"> -  Spatula <span style="color: #0070c0; font-family: Symbol; font-size: 20pt; line-height: 115%; mso-bidi-font-family: Symbol; mso-fareast-font-family: Symbol; msobidifontfamily: Symbol; msofareastfontfamily: Symbol; msolist: Ignore;">· Method: <span style="color: #7030a0; font-size: 16pt; line-height: 115%; mso-bidi-font-family: Calibri; mso-bidi-theme-font: minor-latin; mso-fareast-font-family: Calibri; mso-fareast-theme-font: minor-latin; msobidifontfamily: Calibri; msobidithemefont: minor-latin; msofareastfontfamily: Calibri; msofareastthemefont: minor-latin; msolist: Ignore;"> 1.

Our aim is the rank the reactivity of 5 different metals.

If you are closer to Nobel gases that means you have to gain or lose smaller amount of electrons to be a stable atom. If the electrons started to move than it is called chemical reaction which is we are ranking now. For magnesium, it just has to lose 2 electrons that it was really reactive compare to copper which doesn’t know it has to gain electrons or lose electrons. <span style="color: #0070c0; font-family: Symbol; font-size: 20pt; line-height: 115%; mso-bidi-font-family: Symbol; mso-fareast-font-family: Symbol; msobidifontfamily: Symbol; msofareastfontfamily: Symbol; msolist: Ignore;">· Evaluation: <span style="color: #7030a0; font-size: 16pt; line-height: 115%; mso-bidi-font-family: Calibri; mso-bidi-theme-font: minor-latin; mso-fareast-font-family: Calibri; mso-fareast-theme-font: minor-latin; msobidifontfamily: Calibri; msobidithemefont: minor-latin; msofareastfontfamily: Calibri; msofareastthemefont: minor-latin; msolist: Ignore;"> 1.
