A partial answer covering #3 and #5:
3. BREAKING BAD. This relies on Deuterium, an isotope of hydrogen. Its symbol is usually 'D' and its formula expressed as 2H. A compound of barium and deuterium would therefore be 'BaD', and the rebus shows the bond between these two being broken.
5. GREAT EXPECTATIONS (Charles Dickens). This relies on the statistical formula for calculating expected value or 'expectation'.
It looks like 1,2,3 and 5 have been solved.
Here are the others I think
Electric Relaxation (Electric field with exponential decay)
Previous guess: The Electric Slide
Seven Si-cos = Seven Psychos (also known as Seven Psychopaths in the UK).
To add on:
Lost? (As in an electron was lost)?
Great Expectations? (An expected value/expectation of “VeryGood”, or “Great”)
