Group 1 - The Alkali Metals 3.0 / 5 based on 1 rating ? ChemistryChemical patterns and reactivity seriesGCSEAQA Created by: eloiseCreated on: 17-04-13 18:33 what do they look like? Silvery solids 1 of 10 what are they stored in? oil 2 of 10 as you go down the group.. more reactive and have a lower melting and boiling point 3 of 10 what is their density? Low, first 3 less dense than water 4 of 10 examples.. lithium, sodium, potassium 5 of 10 one outer electron very reactive, similar properties 6 of 10 form ionic bonds with non-metals produce white compounds that dissolve in water to colourless 7 of 10 with water produce hydrogen react vigorously, float, fizz with water 8 of 10 potassium gets hot enough to ignite in water form hydroxides which dissolve in water to form alkaline solution 9 of 10 2Na(s) + 2H20(l) = 2NaOH(aq) + H2(g) 2K(s) + 2H2O(l) = 2KOH(aq) + H2(g) 10 of 10
