What makes the halogen family unique?
The halogens are a group of elements in the periodic table. Elements in the halogen group have seven electrons in their outer shells giving them many unique properties.
What is the characteristics of halogen?
Properties
| HALOGEN PROPERTIES | |
|---|---|
| No halogen is completely colorless. | Typical to non-metals, halogens have very low melting and boiling points. |
| In their solid forms, all halogens have a brittle texture. | Halogens are poor conductors of heat and electricity, irrespective of their physical state. |
