Pessimist vs. Optimist

PROGRESS UPDATE: Saturday 29th December (13:32 PM)

EMOTION: A feeling of doom being desperately veiled by fighting optimism.

WHY: Recently had a dawning realisation of how serious January is going to be, as well as how much work I have to do, which is being fought against by my thoughts of “You still have another week left” and “You might be able to buy some more CDs soon” and “DON’T PANIC”.

CURRENT REVISION TASKS: Currently doing revision for Science exams — Chemistry mock (which I don’t want to do much revision for since I might use up all the revision material for the real exam in May/June) and REAL EXAMS in Physics & Biology.

MOMENTS OF JOY: Bobbing along to Depeche Mode and Yazoo whilst working on SAM Learning; performing my temporary morning exercise — GANGNAM STYLE; lying exhausted on the floor of my room last night as Jean Michel-Jarre’s therapeutic “Oxygene” washes over me.

GREATEST MOMENT SO FAR: Reading up on the New Year Honours List and seeing Higgs, Quentin Blake and Ewan Mcgregor on it, along with all the Olympic heroes.

BIGGEST MOMENT(S) OF ANNOYANCE SO FAR: Getting a ridiculously low grade on a mini test (thank goodness it was only Electrolysis).

BIGGEST SHOCK SO FAR: Hearing and reading of the scurge of the blasted norovirus; it’s bringing out the germophobe in me.

FINISHING SENTENCE: Keep calm and carry on.

Fred’s Chemistry Quiz!

Please do not have a periodic table at hand when doing this quiz, or cheat!

1. What is the first name of the periodic table’s inventor?
2. What is the only Element named after a Continent?
3. What are the four most common elements in the human body?
4. Name the two elements that are liquid at room temperature and pressure (298K/25C, 1atm/101kPa)?
5. Name the orbital that is only partially filled in most actinides and lanthinides?
6. What game was the periodic table supposedly based on?
7. What is the name of the physical structure that Carbon forms when it only has single bonds? (I’m not looking for stuff like Alkanes/Hydrocarbons here, but the name of the 3D shape it forms.)
*8. What form of reaction produces an Alcohol from a Ketone?
9. Cyanide groups in organic chemistry contain which 2 elements? (and bonus point: what is the formula for gaseous Cyanide?)
*10. What is the main use of Cyanide in organic synthesis?
11. What happens to the reactivity when moving down group 2?
12. What is the reason for this trend?
13. What are the first four elements in the periodic table song?
14. Apart from English, what is the most common language for chemistry to be published in?
15. What element is named after a scientist who has also had his name in a that of a science park near Didcot (the location of the Diamond Synchrotron)?
16. What is the last element in group 1?
17. How many sub-shells are there in the 2p orbital?
18. Name the first 5 letters given to orbitals, in the order that they appear (or would appear) in elements (hint: s,p,_,_,_)
19. What does the p in the 2p orbital stand for? (and 4 bonus points if you can say what the other 3 of the first four letters in 18/ stand for!)
*20. What are the first two elements that have a d-orbital but are NOT transition elements?
21. What exists between the metals/transition metals and the non metals in the periodic table?
22. What is the most common use of these elements?
23. What is the charge on most of the ions that cause hard water?
24. What Greek word is Atom derived from?
25. What does this word translate as?
26. What is a proton also known as in Chemistry?
27. What reaction is sped up (catalyzed) by Catalase?
28. What is the proper name for the main component of vinegar? (note NOT acetic acid!)
29. What biological problem does methanol cause?
30. And an easy one to finish: what is the proper name for common alcohol that you find in drinks?

Starred questions are A-Level Qs. But if you are an avid viewer of The Scishow, Bang Goes the Theory, The Secrets of Everything etc, or are an extraordinarily intelligent scientist, then you might know these!

Good luck, and I’ll post the answers in about a week!
