On a side note, today is also MOLE DAY! Happy 6.02 x 10^23!
This week we did a really cool flame test with different kinds of elements like Sodium and Boron.
They emitted different colors of flames when we burned them, such as bright candy red and bright lime green! This is because each element has a unique energy signature that gives off discrete photons when energy is added. In the case of copper, it emits green light because its energy level makes it emit a certain wavelength of light (with a specific amount of energy) that is green!
On another side note, my group accidentally left in the metal hoop for too long and it turned white hot. x_o
