Which group on the periodic table is the least reactive?
In the periodic table, the elements with eight electrons outermost form the group known as the noble gases (Group 18 [0]), the least reactive of the elements. The carbon group elements (Group 14), with four electrons, occupy a middle position. Chemical reactions result from the exchange of electrons among atoms.
What is the least interesting element on the periodic table?
Thulium is among the most obscure elements in the periodic table. It has very few applications. Some people consider it the most useless of all naturally occurring elements, though others will rush to its defense. Scroll down to see examples of Thulium.

What element is most reactive on the periodic table?
Fluorine: The Most Reactive And Indispensable Chemical Element In Our Daily Lives. Fluorine is a remarkable chemical element - not only because of its unique reactivity.
What is the most reactive element and why?
Alkali metals (situated far away from transitional metals and noble gases) are the most reactive elemental group. Cesium is second from the bottom of this group, with 6 electron shells, so it fits all the characteristics of a reactive atom, therefore making it the most reactive element.
What are the most reactive elements in order?

Which metal is highly reactive?
According to reactivity series, sodium is the most reactive metal.
Which of the following is most reactive?
Hence, ICl is most reactive.
Why is group 1 the most reactive?
These are the electrons in their outer energy level that can be involved in chemical reactions. Valence electrons determine many of the properties of an element, so elements in the same group have similar properties. All the elements in group 1 have just one valence electron. This makes them very reactive.
Which is more reactive iron or copper?
Iron is more reactive than copper as copper has less outer shells than iron, so copper is less likely to react with another element as it has a stronger hold over the electrons.
Is oxygen the most reactive element?
8 on the Periodic Table of the Elements is a colorless gas that makes up 21 percent of Earth's atmosphere. Because it's all around, oxygen is easy to dismiss as dull and inert; in fact, it's the most reactive of the non-metallic elements.
What are the two most reactive elements?
The two most reactive groups of elements are the alkali metals and the halogens, because of their valence electrons.
What is the least reactive element?
The least reactive elements are the noble gases. Within this group, helium is the least reactive element, forming no stable compounds. Metal can have multiple oxidation states and tend to have intermediate reactivity.
Is Lithium the most reactive metal?
In a reactivity series, the most reactive element is placed at the top and the least reactive element at the bottom. More reactive metals have a greater tendency to lose electrons and form positive ions ....The reactivity series.ElementReaction with waterLithiumQuicklyCalciumMore slowly2 more rows
Why is Francium the most reactive element?
As there are now more shells between the electron and the nucleus, the outer electron experiences more shielding and therefore less attraction to the nucleus. This means that the outer electron is more easily removed in Francium than other group 1 elements.
Why is group 1 the most reactive?
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.
Why is Caesium the most reactive metal?
Among the alkali metals, Cs is the most reactive because its outermost electron is more loosely bound than the outermost electron of the other alkali metals. This is due to the increase in distance between the outermost electron shell and the nucleus.
Why is fluorine the most reactive element?
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. electron config.
What is Fluorine?
Fluorine is the chemical element with the symbol F and atomic number 9. Its atom is the third smallest among all elements with an atomic radius of 153 pm. It has 9 electrons that surround the nucleus of its atom — 7 in its outer shell, and 2 in its inner shell. Its atomic weight is 18.998403 and its density is 0.001696 g/cm 3.
Applications of Flourine
Fluorine has a wide range of applications and its common use is in the production of sodium fluoride. Sodium fluoride is one of the ingredients added to toothpaste. It is beneficial for the prevention of tooth decay. Fluorine is essential in the production of aluminum, dye, ceramics, and fluorochemicals such as solvents and superplastics.
What Is Chemical Reactivity?
A chemical reaction is a process by which one or more substances are converted into one or more new substances. It occurs when the atoms of one substance react and gain, lose, or share electrons with the atoms of another substance.
Reactivity of Flourine
Fluorine has the highest electronegativity of any element, with a value of 3.98. This means that fluorine, more than any other element, is the most likely to accept electrons. Cesium has the lowest electronegativity of any element at 0.79, making it the least likely to accept electrons, and it even gives its own electrons to others.
Dangers of Flourine
Fluorine is a highly corrosive, toxic, and hazardous substance. It is a very dangerous material, which is why it is only used and produced in laboratories, and it can only be handled by chemists or chemical experts. Simply inhaling this substance can cause breathing difficulties and respiratory tract damage.
