The halogen group of elements is the most reactive of the nonmetals. It is also the most reactive group of all chemical elements. Fluorine is the most reactive element in this group.Know More
Halogens are highly reactive because they are all electronegative. They can gain electrons very quickly which is what makes them react so strongly to other elements. Halogens can form many bonds very fast. Fluorine, for example, only has the choice of losing seven electrons or gaining one, so it almost always gains the one electron since this is much easier. As a result, it often rips electrons away from other elements in order to gain this electron and become stable.
The halogens include fluorine, chlorine, bromine, iodine and astatine. The most reactive element from group seven is fluorine which is at the top of that section of the periodic table. The further down the group you go, the less reactive the element is. Halogens are poisonous to humans on the whole, though each one is poisonous to a different degree. The halogens also tend to be poor conductors of electricity and heat. These chemicals exist at all phases of matter including solid, liquid and gas; they are the only elemental group that has this characteristic.Learn more in Chemistry
Arsenic is not particularly reactive though yellow arsenic is the most reactive and reacts with halogens under controlled conditions, fluorine and slowly with air (oxidization only). Arsenic does not react with water and is not explosive.Full Answer >
According to Encyclopedia Britannica, silver is one of the least types of chemically reactive elements. Silver is a chemical element, and the metal is a lustrous and white color.Full Answer >
The most reactive metals react with water to form hydrogen gas and their oxides or hydroxides, and with acids to form their oxides or hydroxides. According to the activity series, the first nine metals are highly reactive with water and the next six with acids.Full Answer >
Fluorine is the most reactive of the halogens because it is at the top of the halogen group, which is the second to right group on the periodic table. With halogens, the higher an element is in the column, the more reactive it is.Full Answer >
