Which of the following groups in the periodic table contain elements so reactive that they are never found in the free state?
Group 1 (alkali metals) and Group 17 (halogens) in the periodic table contain elements that are highly reactive and are never found in their free state in nature. Alkali metals readily react with water or air, while halogens are highly reactive nonmetals that form compounds with other elements quickly.
Which elements are most likely to react with other elements?
The elements in Group 1 of the Periodic Table are highly reactive in water, and, only slightly less reactive in Oxygen. Group 2 elements are also quite reactive in Oxygen, but not quite as reactive as those elements in Group 1.
What are the 2 most reactive group?
The alkali metals (Group 1) and the halogens (Group 17) are among the most reactive groups on the periodic table. Alkali metals readily react with water, while halogens are highly reactive nonmetals that easily form compounds with other elements.
Why group 1 and group 2 elements do not occur free in nature?
Group 1 and group 2 elements are reactive metals and react readily with water. They also react readily at high temperatures with oxygen. Over the millenia any free deposits would react to form compounds.
Which set of elements make up the reactive group of all metals?
The reactive group of all metals consists of elements located in Group 1 and Group 2 of the periodic table, known as the alkali metals and alkaline earth metals, respectively. These metals are highly reactive due to their tendency to lose electrons and form positive ions.
Which group is more reactive on the periodic table group 1 or 2?
Group 1 elements are more reactive than that of group 2 elements.
Which groups of elements are very reactive?
The alkali metals (Group 1) and the halogens (Group 17) are known to be very reactive elements. Alkali metals react vigorously with water, while halogens are highly reactive nonmetals that readily form compounds with other elements.
How are group 1 elements different from the group 18 elements?
The difference between group 1 and group 2 metals is that group 1 metals have ONE valence electron and group 2 have TWO valence electrons. This makes a great difference in how they react chemically with other elements and compounds.
Which of the following groups in the periodic table contain elements so reactive that they are never found in the free state?
Group 1 (alkali metals) and Group 17 (halogens) in the periodic table contain elements that are highly reactive and are never found in their free state in nature. Alkali metals readily react with water or air, while halogens are highly reactive nonmetals that form compounds with other elements quickly.
Which elements are most likely to react with other elements?
The elements in Group 1 of the Periodic Table are highly reactive in water, and, only slightly less reactive in Oxygen. Group 2 elements are also quite reactive in Oxygen, but not quite as reactive as those elements in Group 1.
Are groups 1 and 2 more or less reactive in periodic table?
Group 1 elements are the most reactive among metals, followed by group 2 elements.
What are the 2 most reactive group?
The alkali metals (Group 1) and the halogens (Group 17) are among the most reactive groups on the periodic table. Alkali metals readily react with water, while halogens are highly reactive nonmetals that easily form compounds with other elements.
How does reactivity change from an element in group 1 to an element in the same period in group 2?
Reactivity decreases from group 1 to group 2 within the same period. Group 1 elements, like lithium and sodium, are highly reactive due to their single valence electron, which they readily lose to form positive ions. In contrast, group 2 elements, such as magnesium and calcium, have two valence electrons, making them less reactive since they require more energy to lose both electrons. Consequently, while both groups are reactive, group 1 elements are generally more reactive than their group 2 counterparts in the same period.
Why group 1 and group 2 elements do not occur free in nature?
Group 1 and group 2 elements are reactive metals and react readily with water. They also react readily at high temperatures with oxygen. Over the millenia any free deposits would react to form compounds.
Which periodic table family consists of highly-reactive elements?
S block has the most reactive elements. The groups 1 and 2 belongs to the s block.
What are the elements are in the first group have 2 outer shell electrons and are also very reactive?
The elements in the first group of the periodic table, known as the alkali metals, have one outer shell electron and are highly reactive. However, the elements with 2 outer shell electrons that are also very reactive belong to the second group, known as the alkaline earth metals. This group includes elements such as beryllium, magnesium, calcium, strontium, barium, and radium. These metals readily react with water and acids, making them quite reactive, though generally less so than alkali metals.
Why goup 2 elements are reactive?
Group 2 elements, also known as the alkaline earth metals, are reactive due to their tendency to lose two electrons to achieve a stable electron configuration similar to noble gases. This makes them highly reactive, particularly with nonmetals like oxygen and halogens. Their reactivity increases down the group as the atomic radius increases, making it easier for these elements to lose their outer electrons. Additionally, the lower ionization energy of these elements compared to those in Group 1 contributes to their reactivity.
