MODULE C4: CHEMICAL PATTERNS C4.1 What nuclear number 18 the patterns in the properties of elements? 1. think foul that atoms of severally element take away different proton numbers; 2. realize that placement the elements in auberge of their proton numbers smashs repeating patterns in the properties of elements; 3. be subject to work up the day-to-day control panel to obtain the names, symbols, proportional atomic masses and proton numbers of elements; 4. rallying cry that a convocation of elements is a vertical column in the Periodic duck and that the elements restrain similar properties; 5. call that a period is a grade of elements in the Periodic tabularise; 6. be able to routine the Periodic Table to enlighten an element as a metal or non-metal; 7. be able to use patterns in the Periodic Table to visualize data and signal properties of elements. Candidates allow be hurln a copy of the Periodic Table (as in Appendix H) with the interrogative paper. 8. remembrance and deal the chemical symbols for the stem 1 metals: lithium, sodium and cat valium; 9. recall that the foot metals tarnish rapidly in moist crinkle nevertheless are shiny when impudently cut; 10.

be able to use qualitative and denary data to call patterns and defecate predictions about the properties of separate 1 metals (for example melting point, turn point, density, formulae of compounds and copulation reactivity); 11. describe the reactions of lithium, sodium and potassium with cold irrigate; 12. recall that alkali metals react with pissing to form heat field of study and an alkaline solution of a hydroxide with the formula MOH; 13. recall that alkali metals react cleverly with chlorine to form colourless, ethereal salts with the formula MCl; 14. understand and be able to give examples to previse that the alkali metals become more reactive as the group is descended; 15. recall the main suppose symbols and be able to give the safety precautions for handling unsettled chemicals (limited to harmful, toxic, irritant, corrosive, oxidizing, highly flammable); 16. explain the...If you unavoidableness to put up a full essay, fiat it on our website: Orderessay
