S8 chain 3 of 9 H2O2 prone to disproportionation - what is this? Decreasing and increasing O.S at same time 4 of 9 Oxides of group 16 SO2 = gas. SeO2 = solid chain. TeO2 = double chain 5 of 9 Aufbau principle? Fill lowest available energy levels first 6 of 9 acidity of oxoacids determined by what? (HnXOm) If X=e- accepting - stronger acid (H-O weaker). More acidic if substituent = EWG. Stronger if more oxygens to delocalise. -ve species = weaker acid 7 of 9 Why can't noble gases be frozen through T alone? Need pressure due to weak IMFs. 8 of 9 Properties of noble gases High IE. High Zeff. EA close to 0. Below 2.2K, He = superfluid. Xe and Kr form compounds with most electronegative elements 9 of 9
