Fluorine is a most reactive element in group 17 because of its small size and high electronegativity by which it accepts electrons easily and forms a bond with another element.

Where are the most active elements?

bottom left corner
The elements toward the bottom left corner of the periodic table are the metals that are the most active in the sense of being the most reactive.

Why is fluorine the most active element in group 17?

Fluorine (F), most reactive chemical element and the lightest member of the halogen elements, or Group 17 (Group VIIa) of the periodic table. Its chemical activity can be attributed to its extreme ability to attract electrons (it is the most electronegative element) and to the small size of its atoms.

What group has the most active element?

Lithium is the most active element in the periodic table. Explanation: The periodic table is composed of 18 groups and 7 periods. The reactive ability of the elements shows variation in groups and periods.

Why are groups 1 and 17 the most reactive?

Elements in group 17 include fluorine and chlorine. Group 1 of the periodic table includes hydrogen and the alkali metals. Because they have just one valence electron, group 1 elements are very reactive.

Which property increases down group 17?

Halogens are nonmetals in group 17 (or VII) of the periodic table. Down the group, atom size increases. As a diatomic molecule, fluorine has the weakest bond due to repulsion between electrons of the small atoms. Due to increased strength of Van der Waals forces down the group, the boiling points of halogens increase.

Which is the longest period?

sixth period
The sixth period is called the longest period because it has maximum 32 elements.

Why is Group 17 so reactive?

Halogens are nonmetals in group 17 (or VII) of the periodic table. Due to their high effective nuclear charge, halogens are highly electronegative. Therefore, they are highly reactive and can gain an electron through reaction with other elements.

What are the group 17 elements in the periodic table?

But, do you know that the Group 17 elements in the periodic table are called “halogens”. Why? Well, we will find out soon! In this chapter, we will cover all about halogens, their properties, and uses. The group 17 elements include fluorine (F), chlorine (Cl), bromine (Br), iodine (I) and astatine (At) from the top to the bottom.

Why are halogens more reactive than other group 17 elements?

Reactivity. The easier the atom of a halogen gains one electron, the more reactive is the halogen, Explanation: The decrease in the reactivity down Group 17 can be explained as follows. All halogens have seven valence electrons. Each halogen atom will gain one electron to achieve a stable octet electron arrangement.

Which is the most powerful oxidizing agent in Group 17?

Of the list, fluorine is the most powerful oxidizing agent. It is capable of oxidizing all the halide particles to halogen. The oxidizing power reduces as we move down the group. The halide particles also act as reducing agents. However, their reducing capacity decreases down the group as well.
