Introduction

States of Matter SOLID LIQUID GAS Atoms Al Electrons orbit the nucleus, it does this in shells, 1st shell holds a max of 2 electrons, after that shells hold up to 8 electrons. Proton = positive Neutron = neutral Electron = Negative Isotopes- atoms that are the same but can vary in the number of neutrons but have the same amount of protons. e.g. C C C IONIC BONDING In general metal atoms lose electrons to form positive ions and non- metal atoms gain electrons to form negative ions. An ionic compound is formed when a metal atom joins with a non-metal atom. An electron is lost from sodium and gained in the Clorine making them both have full outer shells. Compounds with giant ionic structures * Made of crystals * Usually have high M.P. ...read more.

Middle

- Gas (aq) - aqueous solution(dissolves in water) IONS Some ions contain more than one element e.g. NO3 (-) but the same rules apply as in simple ions. Brackets are needed when more complex ions are involves e.g. Fe(3+) + NO3(-) Fe(NO3)3 elements tend to be positive ions and compounds negative ions. ELEMENTS AND COMPOUNDS If you have one metal and one non-metal the compound will end in "ide". e.g Magnesium + Oxygen Magnesium oxide If you have two non-metals the compound will end in "ate" e.g. Copper + sulphur Copper sulphate + Oxygen The numbers in a formula show the amount of each kind of atom in the compound or element. e.g. H2 two hydrogen atoms BALANCING EQUATIONS * Chemical reactions are really re-arrangements of atome reactant substances that have their atoms re-arranged and they become product substances. ...read more.

Conclusion

* Alkali metal compounds are white when solid an colourless in a solution, soluble, they have a PH above 7, i.e. alkali Halogens are in group 7 Flourine Chlorine Bromine Iodine yellow green red/brown Purple gas gas solid liquid Fl2 Cl2 Br2 I2 A Halide is formed when a Halogen is in an equation. TRANSITIONAL METALS * Found between groups 2 and 3 * Can form oxides with two different formulas both oxides formed are colourless * Transitional metals and their compounds make good catalysts. Uses: Iron - man hole covers Copper - water pipes Nickel - coins Titanium - aircraft industry SODIUM CHLORIDE Can be ontained from collecting sea water and allowing water to evaporate leaving salt. Formula = Na + Cl NaCl Substance Uses Chlorine solvents, bleeches, kills bacteria in pools and drinking water, whitens paper Hydrogen Combines with oxygen to form water Sodium Hydroxide Soap, detergents, paper ...read more.

    Find the beaker with Na+ 0. Dip the spatula in Na+, so little adheres (Not too much) 0. Hold the spatula in Bunsen flame- Important use eye protection! 0. Observe the colours of the flame and record on the table.

  2. Rate of reaction of hydrochloric acid on magnesium.

    I have come to a conclusion that as the concentration of HCl had increased the gas produced at each time interval had also increased therefore the rate of reaction was fast. As I had mentioned before the primary factor to rate of reaction is the amount of reacting particles in a solution.

  1. Our experiment consisted of two samples of water containing unknown substances, and our objective ...

    In order to do that, we had to carry out a series of tests. To save time and effort, we didn't have to extract the solid from the evaporating basin. Instead, we were given the two substances. This made it easier for us because it gave us more time to do the tests, since there were a lot.

  2. should salt be banned?

    Most people don't know. "Most people buy just whatever one their hand grabs... and until about five years ago, it didn't really matter," says Glen Maberly, MBBS, MD, an endocrinologist and professor of international health in the Rollins School of Public Health at Emory University School of Medicine in Atlanta.

  1. Identification of an unknown compound.

    with a white precipitate occurred in test one and this proved that a phenol was not present. Then the orange/red precipitate that formed when the 2,4-dinitrophenylhydrazine was added indicated that an aldehyde or ketone was present. The final experiment with tollens reagent (ammoniacal silver nitrate)

  2. Rate of reaction of different concentrations of sodium thiosulphate.

    By diluting water it will decrease the concentration of Na2S2O3 so in parallel the rate of reaction will also decrease. I will measure the concentration of Na2S2O3 by the unit g/dm3. The Dependent variables in the experiment would be the temperature and hydrochloric acid.

  1. Particulate Nature of Matter

    The common point about solids is that the atoms or molecules are in place. The temperature that can be shown by solid materials is due to the movement in place of the atoms or molecules. They have no independent linear motion of translation because they are attached to one another.

  2. Antimatter and matter

    that can be reversed. You`d be forgiven for thinking that an American predicted anti-matter. Or that it only existed in Star Trek. In fact, it was Paul Dirac, a Bristol born physicist, who predicted the stuff that propels starships in science fiction movies and who has also influenced much of our modern day technology, for example, computers.
