Group 16 name
the chalcogens
1 of 9
O2 appearance at low temps?
pale blue liquid or solid
2 of 9
S common form?
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
