I agree with Hephzi, after years of working with chemicals one becomes familiar with their symbols. I can tell you roughly where most things are but I don’t think I’d get the order correct. I carry a periodic table around with me in my wallet so I can always look something up!
The position No. That would be really tricky. I can have a darn good guess at most of the element symbols. I have a free app on my phone if all else fails 😛
No – I used to know a lot of them when I was at school but unfortunately I’ve forgotten since then. I’m not the kind of scientist that works with chemicals so this isn’t as important for me, but I can have a good go at naming different parts of the brain instead!
