The most chemically active element is the halogen known as fluorine.

Fluorine, F, is the most reactive element of all.
Fluorine, chlorine, bromine, iodine, and astatine. All of the elements in the halogen family are nonmetals.
This refers to an old "history of science " topic around the work done prior to mendeleevs on periodic table. Elements were put in triads with similar properties. The halogen triad was chlorine, bromine and iodine. Pretty useless idea long term but a good start for people who came later.
Bromine is classified as a p-block element because its highest energy electrons are in the p orbital. This means it has electrons in its outermost electron shell which are involved in chemical reactions. Bromine is located in group 17 of the periodic table, known as the halogen group, which contains elements that exhibit similar chemical properties.
The most active nonmetals on the periodic table are typically found in Group 17, also known as the halogens. This group includes elements such as fluorine, chlorine, bromine, and iodine, which are known for their high reactivity and tendency to form compounds with metals.
Fluorine, F, is the most reactive element of all.
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.
Halogens are in the group 17 of the periodic table of Mendeleev.
The elements found in halogen has very rarely been known to cause any type of environmental issues. Because of this, there is very little information about halogen as a pollutant.
Now are known 118 chemical elements.
Bromine is the official name for BROMINE. It is an halogen element. However, it does form bromides, bromates, when combined with other elements.
The halogen family, which includes elements like fluorine, chlorine, bromine, iodine, and astatine, is located in Group 17 of the periodic table. Group 17 is also known as the halogen group because all its elements are halogens.
The force that attracts chemical elements to other elements is known as the ionic bond. This will attract and hold chemical elements together.
The smallest particles of elements that enter into chemical reactions are known as atoms.
Fluorine, chlorine, bromine, iodine, and astatine. All of the elements in the halogen family are nonmetals.
Now (22.08.2012) 118 chemical elements are known.
Today are known 118 chemical elements.
