Flashcards made for 2025-2028 exams from the textbook and SME, AS Level CIE Chemistry
| Front | descreibe the solubility of group two oxides |
| Back | solubility increases down the group |
| Front | Describe the combustion of an Alcohol |
| Back | Alcohol+O2->CO2 + H2Oburns with clean blue flame |
| Front | what is the trend for ionic radius in period 3 |
| Back | -from group 1-4 metal ions loose elecetron and become positive, ionic radius will decrease-from group 4-5 there is a rapid increase in ionic radius as element will begin to gain electrons-from group 5-7 ionic radius will decrease as element gain electrons (there is an decrease across the period as less electrons are gained there is less repulsion between electrons so the radius is smaller) |
