Halogens are a group of elements that include fluorine, chlorine, bromine, and iodine.
These elements are special because they have bright colors.
One reason for their colorful properties is how their electrons act.
As you go down the list from fluorine to iodine, the size of the atoms gets bigger, and they have more electron shells.
This change affects how they take in and give off light.
Here are some important points to remember:
Electron Jumps: Electrons can move up and down between different energy levels. When they jump back down, they give off specific colors of light.
Colorful Compounds: Halogens can make different compounds that have bright colors. The strength of these compounds changes as you move down the group.
State of Matter: Fluorine and chlorine are gases, bromine is a liquid, and iodine is a solid. This difference also adds to their unique colors.
Overall, halogens are a great example of how the way something is built can change how it acts!
