Which element is least reactive in Group 1?


Lithium (Li) is the least reactive alkali metal, while francium (Fr) is the most reactive, indicating that the reactivity of alkali metals rises as one moves from their top to its bottom of the group.


As a result, it is possible to inquire as to which collection of components is the least reactive.

Noble Gases are classified under Group 18 of the periodic table. Noble gases are nonmetals that belong to the Group 18 elements (see Figure below). All of these gases are colourless and odourless. Because their outer energy level is similarly full, they are the least reactive of the elements in the periodic table.


Second, which element in Group 7 has the least amount of reactivity?

As you go down the group, the non-metal elements in Group 7 – known as the halogens – become less reactive as the group number increases. This is the polar opposite of the pattern shown in the alkali metals of Group 1 of the periodic table, which is increasing. Fluorine is the most reactive element in Group 7 of the periodic table.


Which of the following groups of elements is the least reactive, and why?

Noble gases are the least reactive of all the elements in the periodic table. The reason for this is that they contain eight valence electrons, which are responsible for filling their outer energy level. Noble gases seldom combine with other elements and form compounds because this is the most stable arrangement of electrons.


Was there a general upward trend in the reactivity of Group 1 with water?

The elements in group 1 are all soft, reactive metals with low melting temperatures, and they are all composed of carbon. A alkaline metal hydroxide solution and hydrogen are formed as a result of their reaction with water. The level of reactivity rises as one moves down the group.

Which element has the most reactivity?

It has been shown that fluorine is the most electronegative element in the periodic table, making it the most potent oxidising agent on the planet. It is the non-metal with the highest level of reactivity. Considering how reactive fluorine is, it has the ability to burn things that are often considered non-flammable!


Which group has the highest level of reactivity?

Because of their valence electrons, the alkali metals and the halogens are the most reactive groupings of elements, followed by the transition metals. Those groups have only one and seven valence electrons, respectively, making them desperate to bond to something in order to achieve a stable configuration of eight electrons.


Which metal has the highest level of reactivity?



Which nonmetal element has the highest level of reactivity?

Fluorine is the nonmetal with the highest reactivity. Fluorine is a halogen, which belongs to Group 17 of the periodic table, and halogens are the nonmetals that are the most reactive. This is due to the fact that they all have one vacant electron shell in their valence electrons.


Who was it that discovered halogens?

Scheele referred to the element as “dephlogisticated muriatic acid,” which was the name by which chlorine was known for 33 years before the discovery of the element. Humphry Davy conducted research on chlorine in 1807 and determined that it is a real chemical element.


Which element in Group 2 has the lowest reactivity?

Lithium (Li) is the least reactive alkali metal, while francium (Fr) is the most reactive, indicating that the reactivity of alkali metals rises as one moves from their top to its bottom of the group. Because alkali metals are very reactive, they can only be found in nature in conjunction with other elements due to their reactivity.


What is the best way to determine which element is the least reactive?

The reactivity of an atom is determined by the amount of electrons present in its outermost shell. Noble gases have limited reactivity because their electron shells are completely filled. Halogens are extremely reactive because they rapidly obtain an electron to occupy their outermost shell, which causes them to become more reactive.


What is the total number of valence electrons in group 7?

The valence electrons in Group 5 atoms are all five in number. The valence electrons in the atoms of Group 6 total six. The Group 7 atoms contain 7 valence electrons.


Are halogens a flammable substance?

They are all elements that can be found in the group 17 of the periodic table, which is composed of halogens. Fluorine, chlorine, bromine, iodine, and astatine are some of the halogen elements. All of these elements are classified as reactive nonmetals, which means that they are highly reactive. The fact that these atoms are so close to possessing a complete set of eight valence electrons makes them extremely reactive.


What can I do to become less receptive?

What you can do to be less emotional reactive Begin by cultivating awareness. There is a pause between the stimulus and the response. Identify the emotions you’re experiencing. For dealing with strong emotions, there is a well-known and effective approach known as “Name it to Tame it.” Concentrate on what is most important. Count to a maximum of ten. Respond, rather than reacting.


Is reactivity a chemical property?

When matter undergoes a transformation to become a completely other sort of matter, chemical characteristics may be measured or detected for the first time. Reactivity, flammability, and the ability to rust are among of the characteristics. The capacity of matter to react chemically with other substances is referred to as reactivity.


Which two families have the highest level of reactivity?

The halogens and alkali metals are the two most reactive families of elements, with the halogens being the more reactive of the two.


Which halogens are the most refractory in nature?

According to a general rule of thumb, fluorine is the most reactive of the halogens, while astatine is the least reactive. All of the halogens combine to generate Group 1 salts, which have comparable characteristics. Halons are present in these compounds as halide anions, which have a charge of negative one (e.g. Cl-, Br-, etc.).


Which of the elements in group 7 is the most reactive?
