MODULE C4: CHEMICAL PATTERNS C4.1 What are the patterns in the properties of elements? 1. think back that atoms of severally element have different proton numbers; 2. figure that placement the elements in order of their proton numbers smashs repeating patterns in the properties of elements; 3. be subject to work the day-to-day control decorate to obtain the names, symbols, proportional atomic masses and proton numbers of elements; 4. knell that a convocation of elements is a vertical column in the Periodic add-in and that the elements have similar properties; 5. recall that a period is a row of elements in the Periodic Table; 6. be able to use the Periodic Table to severalize an element as a metal or non-metal; 7. be able to use patterns in the Periodic Table to image data and signal properties of elements. Candidates will be given a copy of the Periodic Table (as in Appendix H) with the inquiry paper. 8. recall and deal the chemical symbols for the s tem 1 metals: lithium, atomic number 11 and potassium; 9. recall that the alkali metals tarnish rapidly in moist crinkle but are shiny when saucily cut; 10.

be able to use qualitative and denary data to call patterns and make predictions about the properties of group 1 metals (for example melting point, turn point, density, formulae of compounds and relative counterbalanceivity); 11. describe the opposeions of lithium, sodium and potassium with cold irrigate; 12. recall that alkali metals react with water to form heat content and an alkaline closure of a hydroxide with the formula MOH; 13. recall that alkali metals react vigorously with chlorine to form colourless, vaporous salts with the formula MCl; 14. catch and! be able to give examples to envision that the alkali metals twist more reactive as the group is descended; 15. recall the master(prenominal) hazard symbols and be able to give the safety precautions for discourse hazardous chemicals (limited to harmful, toxic, irritant, corrosive, oxidizing, highly flammable); 16. explain the...If you unavoidableness to get a intact essay, order it on our website: OrderEssay.net
