Group 17 Elements: The Halogens
Christyna.H & Nijayah.C
Description of each Element
What they all have in common
Group 17, or the Halogen Group, all have 7 valence electrons and will gain or share an electron when forming compounds with other elements. They are all non-metals except for astatine, which is a metalloid. They are the most reactive non-metals because they only need one more electron to fill the outer shell.
Interesting Facts about Element 17
- All halogens are electronegative : they gain electrons very quickly, making them the most reactive of all chemical elements.
- Fluorine are used in non- stick Teflon pans.
- Halogen means "salt come to be" and it's significant because halogens form salt when reacted near metal.
- Halogens were names by a Swedish chemist by the name of Jöns Jakob Berzulíus
