I spent all night trying to nod off. I just can’t do it. So tired. But not sleepy.
Having a splitting headache now. I think I shall give up on sleep.
Spent the goodly part of 5 minutes wondering why transition metals are coloured. All because some asked it on a friend’s tag-board.
My reply:
Hmm.. I think it’s because transition metals are defined by those having incomplete d orbitals? as light passes through them, energy is utilised in “promoting” electrons. as energy is siphoned off from the light, the wavelength of the white light changes, causing a change in colour. of course, i could be totally wrong. just my own supposition. Haha. I miss math and sci.
I really do miss math and science. And sleep.
Edit: Can anyone tell me if I’m right? I’m too meh to google
I dunno about that cos I’m too lazy to Google, too, but insomnia is spelled with only one M.

intentional.
Whee! It’s also vair much not mine. I’m designing soon.

well actually. all transition metals except for copper are white in its raw state (as in pure metal). it is only when they complex do they form coloured compounds/complexes due to as you semi mentioned, the ability of the complex to absorb light in the visible section of the electromagnetic spectrum and hence the unpaired electrons moving to the higher energy state.

yay! Yeah, i realised I left out the ions bit. You did mean them, right? Thanks!

Ooh! Pretty diagrams! Naah. I’m never gonna be studying math and sci again. This was just something random.
