Hey in science today we were learning about the electron configuration spectrum and im a little confused. Im not sure becuase we dipped copper chloride wire i believe it was in an assortment of chemicals and and put them over the bunsen burner and they turned pretty colors. Im sopposed to right a one page report on how the electron configuration affects the light of a chemical and im kind of lost in my own thoughts can anyone help

Wasn't a platinum wire with some sort of handle on it? That should be the thing for flame tests since it doesn't interfere.

You dip the wire into a sample of a solution, and then put it in the flame. The flame will turn to a certain color until the solution is burned off, then you clean the wire and repeat with the next one.

The flame excites the electrons and moves them to higher energy levels. As they move back to their normal 'ground' state some of the excess energy is given off as light. Each element will give off a different color of the spectrum- Copper gives a greenish color, sodium has a yellow flame, others have their own distinct colors as well.

Same as a fireworks show really. The colors are made the same way- burning small flakes of certain metals.

You can do the experiment with a pickel soaked in a salt solution and then electrocuting it. Kids like that one as well.

It transports proteins, the roguh endoplasmic is ribosomes attached to the reticulum IIRC
