Fluorine is the most active member of the halogen family because it has the highest electronegativity and is highly reactive, readily forming compounds with other elements.
Bromine is chemically active. It is a halogen and readily forms compounds with other elements, making it reactive in chemical reactions.
When an active metal (such as sodium or potassium) is combined with a halogen (such as chlorine or fluorine), they undergo a redox reaction to form an ionic compound known as a metal halide. This reaction is often highly exothermic and can be violent if not controlled properly due to the high reactivity of both the metal and the halogen.
Bromine is the only liquid halogen at room temperature.
The halogen in period 6 is astatine. It is a radioactive element and is the rarest naturally occurring halogen on Earth.
Fluorine
The most chemically active element is the halogen known as fluorine. Be
Fluorine is the most active member of the halogen family because it has the highest electronegativity and is highly reactive, readily forming compounds with other elements.
The alkali group of metals is the most active.
Iodine has more radius. It has least attraction for electron.
Bromine is chemically active. It is a halogen and readily forms compounds with other elements, making it reactive in chemical reactions.
Fluorine is the most active halogen. It is highly reactive and can form compounds with almost all other elements.
When an active metal (such as sodium or potassium) is combined with a halogen (such as chlorine or fluorine), they undergo a redox reaction to form an ionic compound known as a metal halide. This reaction is often highly exothermic and can be violent if not controlled properly due to the high reactivity of both the metal and the halogen.
The halogen with the least-negative electron affinity is astatine. Electron affinity and electronegativities decreases down a group. Since astatine is the last halogen located in Group 17 as you move down the column from fluorine, it has the least negative electron affinity.
No, it will not be. You will need at least a 50 watt halogen for outdoor lighting.
The Halogen Pharmacy Lamp has a no tip base.
A metal and halogen react to form an ionic bond in which the metal gives an eletron to the halogen Most basic example would be table salt NaCl NaOH + HCl = NaCl + H20
