Ankit Shingala Dr. Campagnolo Chemistry H September 24‚ 2013 Lab on Density of Four Metals Conclusion In this lab we studied the densities of four different metals using a caliper‚ a digital scale‚ and a calculator. Three metals were pure elements like copper‚ iron‚ and aluminum. The fourth metal was an alloy which was brass. The purposes of this lab were to demonstrate that different metal elements have different densities‚ and that alloys have densities somewhere between those elements that

the identity of the metals‚ I was capable of deducing a definite‚ possible identity for the golden metal‚ however‚ I could not provide a definite‚ possible identity for the silver metal. Conversely‚ the results of the experiment themselves‚ whether volume‚ mass‚ or density‚ proved insufficient in my attempts to distinguish the identities of the metals. Thus‚ during the experiment‚ I also observed the color of the metals‚ and used these observations in my assessment of the metals. The five trials for

Chemistry Practical: Activity Series of Metals Introduction: The chemical activity of a metal is directly related to its practical use. In this investigation you will investigate the chemical activity of metals with oxygen‚ water‚ acid and alkali‚ to rank metals in order of their activity. Aim: To observe the reactivity of metals in order to determine the activity series of metals. Risk Assessment: In this investigation‚ hydrochloric acid solution is used which is toxic by all routes of

Transition Metals 1a) The d-orbitals of a free transition metal atom or ion are degenerate (all have the same energy.) However‚ when transition metals form coordination complexes‚ the d-orbitals of the metal interact with the electron cloud of the ligands in such a manner that the d-orbitals become non-degenerate (not all having the same energy.) The way in which the orbitals are split into different energy levels is dependent on the geometry of the complex. Crystal field theory can be used to predict

The alkali metals are found in group 1 of the Periodic table. They are very reactive metals and do not occur freely in nature. Alkali metals are malleable‚ ductile‚ and are good conductors of heat and electricity. Alkali metals can also explode if they are exposed to water. The Alkali metals are: lithium‚ sodium‚ potassium‚ rubidium‚ cesium‚ and francium. Lithium The mineral petalite‚ which contains lithium‚ was discovered by a Brazilian scientist named Jose Bonifacio towards the end of the

[1.] Tungsten is classified as a "Transition Metal" which is located in Groups 3 - 12 of the Periodic Table. An element classified as transition metals are ductile‚ malleable‚ and able to conduct electricity and heat. Tungsten is mixed with carbon to make a very strong‚ very resistant material called tungsten carbide. Tungsten carbide is used to

Ground state- normal configuration of the electrons about the atom or the ion of an element; stable particle electrons are at lowest possible energy level Excited state- when stable particles are heated to very high temperatures some of the electrons leave their ground state and become “excited”; these electrons move to higher energy levels 3.
