A metal is defined as an opaque shiny element which possesses properties such as malleability and ductility. Malleable meaning that they can be hammered into shapes and ductile meaning they can be drawn into wires. They are also very strong and posses high tensile strength and are good conductors of heat and electricity. Metals are shiny‚ and also have high densities. Metals are a very important and significant part of chemistry. However‚ their importance is not just limited to chemistry; they are

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

Coconut Shells as a Shoe Polish Science Investigatory Project Let us begin our adventure with our Abstract... The study focused in making a specialized shoe polish from burned dried coconut husk. It aimed to prove the affectivity of the product in terms of some parametric measurements based on the preferences made by respondents. The parameters were adapted from written reviews for top commercial products. Also‚ this was made to test if there are really no significant difference between the

Polish Migration to the UK Polish migration to the UK began in the year 2004‚ when Poland joined the EU. People were moving from Poland to the UK in search of jobs and better pay‚ because there was shortage of work in Poland and the pay was not good‚ some people only being paid £4 a day whereas in the UK people were getting £400 a day. They were doing jobs that British people did not want to do such as plumbing‚ cleaning‚ building and driving‚ Polish people were generally very hard workers and

domesticum) exudes a white sap/latex containing mosquito repelling triterpenes (lansionic acid p.e.). The dried peel is burned and produces an aromatic‚ white smoke (white from the sap and some remaining water). According to what we have researched the peelings of lanzones have this aromatic smell that drives away and kills‚ mosquito‚ the smoke of this repellant for the smoke is a good agent in making mosquito repellant. This may be a cheap alternative to de-fogging and fumigation against dengue-carrying

Alkali Metals Introduction Alkali metals refer to six elements belonging to the Group IA of the long form of the Modern Periodic Table‚ viz. Lithium (Li)‚ Sodium (Na)‚ Potassium (K)‚ Rubidium (Rb)‚ Cesium (Cs) and Francium (Fr). Fr is a radioactive element. These elements are called so because they form strongly alkaline oxides and hydroxides. Electronic Configuration of Alkali Metals Each of the alkali metals has one electron in their outermost (valence) shell‚ which is just outside an inert

EXTRACTION OF METALS SUMMARY Most metals exist in compounds in rocks in the Earth’s crust. Many of these ores contain oxides or sulphides of the metals. The compounds need to be reduced to produce the metals as elements. Metals are very useful to us because of their special properties. Reduction means removal of oxygen or gain of electrons. Carbon is a good chemical reducing agent because it readily combines with oxygen‚ but it is only useful for the metals below it in the Reactivity
