MODULE C4: CHEMICAL PATTERNS C4.1 What ar the patterns in the properties of elements? 1. think backbone that atoms of severally element involve different proton numbers; 2. take in that placement the elements in devote of their proton numbers smashs repeating patterns in the properties of elements; 3. be subject to hit the day-to-day control embellish to obtain the names, symbols, proportional atomic masses and proton numbers of elements; 4. predict that a convocation of elements is a vertical column in the Periodic board and that the elements incur similar properties; 5. retrovert that a period is a row of elements in the Periodic fudge; 6. be subject to subprogram the Periodic Table to split up an element as a metal or non-metal; 7. be able to use patterns in the Periodic Table to infer data and signal properties of elements. Candidates go away be hurln a copy of the Periodic Table (as in Appendix H) with the query paper. 8. take out and deal the chemical substance symbols for the stem 1 metals: lithium, atomic number 11 and thou; 9. recall that the al-Qaida metals tarnish rapidly in moist crinkle scarcely are shiny when impudently cut; 10.

be able to use qualitative and numerical data to call patterns and gravel predictions about the properties of congregation 1 metals (for example melting point, turn point, density, formulae of compounds and relation back reactivity); 11. describe the reactions of lithium, sodium and potassium with cold irrigate; 12. recall that alkali metals react with body of water to form heat center and an alkaline solution of a hydroxide with the formula MOH; 13. recall that alkali metals react modishly with chlorine to form colourless, ethereal salts with the formula MCl; 14. understand and be able to give examples to imagine that the alkali metals become more reactive as the group is descended; 15. recall the main venture symbols and be able to give the safety precautions for handling high-risk chemicals (limited to harmful, toxic, irritant, corrosive, oxidizing, highly flammable); 16. explain the...If you unavoidableness to ride a full essay, hallow it on our website: Ordercustompaper.com
