Group 17, also known as the halogens, consists of the elements fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). In order from least reactive to most reactive, the elements are iodine, bromine, chlorine, and fluorine, with astatine being the least reactive among them. Fluorine is the most reactive halogen due to its high electronegativity and small atomic size.
What else can I help you with?
Are group one or group two more reactive?
Group one elements are generally more reactive than group two elements. This is because group one elements have one electron in their outermost shell, making them more willing to react and form compounds in order to achieve a stable electron configuration. Group two elements have two electrons in their outermost shell, which makes them less reactive than group one elements.
Which list has the classes of elements in order from most reactive to least reactive?
The order of reactivity among classes of elements typically follows this pattern: alkali metals (most reactive), alkaline earth metals, transition metals, metalloids, nonmetals, and noble gases (least reactive). Alkali metals, such as lithium and sodium, readily lose electrons, making them highly reactive, especially with water. Alkaline earth metals are also reactive but to a lesser extent, while noble gases are largely inert due to their complete electron shells.
What is the group order of alkali metals by reaction?
Francium is the most reactive chemical element; unfortunately is extremely rare and currently not available for chemical experiments. Also is very radioactive. Lithium, Sodium, Potassium, Rubidium, Caesium, Francium
What is the order of reactivity in group 1?
potassium sodium calcium magnesium aluminium (carbon) zinc iron lead (hydrogen) copper silver gold platinum
What is the correct order from most reactive to least in platinum copper and silver?
Yes. Platinum is one of the least reactive metals.

Place these elements in order from leat reactive yovmost reactive neckel xenon lithium how did you determine the order?
In order from least reactive to most, the order is xenon, nickel, then lithium. I determined this based in the theory that non-metals are less reactive.
What is the most reactive group of elements in the periodic table?
The alkali metals, group 1 elements, are the most reactive group of elements in the periodic table. They readily lose their outermost electron to achieve a stable electron configuration, resulting in highly reactive behavior.

Alkaline earth metals are also reactive but to a lesser extent, while noble gases are largely inert due to their complete electron shells.
What is the order of reactivity of alkaline earth metals?
The order of reactivity of alkaline earth metals decreases down the group. This means that the reactivity decreases as you go from beryllium to radium. Beryllium is the least reactive, while radium is the most reactive.
What is the group order of alkali metals by reaction?
Francium is the most reactive chemical element; unfortunately is extremely rare and currently not available for chemical experiments. Also is very radioactive. Lithium, Sodium, Potassium, Rubidium, Caesium, Francium
What is the link between displacement reaction and the reactivity series?
the reactivity series lists elements in order from most reactive to least reactive. in a displacement reaction, a more reactive element will "displace" a less reactive element in a compound, the reactivity series can therefore be used to determine which displacement reactions are possible.
What is the order of reactivity in group 1?
potassium sodium calcium magnesium aluminium (carbon) zinc iron lead (hydrogen) copper silver gold platinum
What is the correct order from most reactive to least in platinum copper and silver?
Yes. Platinum is one of the least reactive metals.
Why are all of the elements in group 18 relatively unreactive Where is those in group 17 are very reactive?
Elements in group 18 (noble gases) have full valence shells, making them stable and less likely to gain or lose electrons. In contrast, elements in group 17 (halogens) have one less electron needed to complete their outer shell, making them reactive in order to gain that electron and achieve stability.
What elements are more reactive than lead?
In the group 2 elements, the reactivity of the metals increase as you move down the group. The order of reactivity in group 2 is barium, strontium, calcium, and magnesium.
Iodine is a highly reactive blank metal gas?
Iodine is not a metal, and not a gas. It is a representative element in Group 7A of the Periodic table of elements. This group is called the halogen group. Iodine is reactive because it wants to gain one more electron in order to fill its valence shell.As far as properties of elements go, "metal-like" properties of elements increase as you go down a group. Iodine is not a metal but is more metal-like than the halides above it in its group ( it is a liquid, they are a gas. Liquid is closer to metal than gas is.)
