What is the connection between the color of an element and its position on the periodic table?
Regarding chemicals such as copper, calcium, nickel, etc.
And can anyone provide any links that could explain this? I can't find anything online.
Help is appreciated. I really need it!!
Most transition elements exhibit an array of different coloured ions and oxidation numbers. This is because they loose electrons from both the 3d and 4s orbitals. Most other metals only produce a colourless ion.
Thats all i know.
