Which is the hardest metal in group 1 that is in alkali metals?
Francium is considered the hardest metal in Group 1 (alkali metals). It is the most reactive alkali metal and is very rare in nature. Due to its high reactivity and radioactive nature, it is challenging to study and handle francium.
What is the reactivity trend of the alkali metals in group IA?
The reactivity of alkali metals in Group IA increases as you move down the group from lithium to cesium. This trend is primarily due to the decreasing ionization energy, which makes it easier for these metals to lose their outermost electron. As the atomic radius increases, the outer electron is further from the nucleus and experiences less electrostatic attraction, leading to higher reactivity. Therefore, cesium is more reactive than lithium.
3 How does reactivity change as you go down Group 1 Does the same pattern hold for group 2?
As you go down Group 1 (alkali metals), reactivity increases due to the lower ionization energy, making it easier for these metals to lose their outermost electron. In contrast, Group 2 (alkaline earth metals) also shows an increase in reactivity down the group, but the trend is less pronounced compared to Group 1. This is because while ionization energy decreases, the presence of two outer electrons means that the reactivity is not solely dependent on losing one electron. Overall, both groups exhibit increasing reactivity down the group, but the rate of change is stronger in Group 1.
Where and what side on the periodic table is more active?
The most active elements on the periodic table are found on the left side and in the bottom rows, specifically the alkali metals (Group 1) and the alkaline earth metals (Group 2). Alkali metals, such as sodium and potassium, are highly reactive, particularly with water, and their reactivity increases as you move down the group. In contrast, halogens (Group 17) on the right side of the table are also very reactive, with reactivity decreasing down the group. Overall, reactivity trends vary depending on whether the elements are metals or nonmetals.
What is the reactivity of group 1 2 A A A A A A?
Group 1 elements, known as alkali metals, are highly reactive, especially with water and halogens, due to their single valence electron. Their reactivity increases down the group, with lithium being the least reactive and cesium the most. Group 2 elements, or alkaline earth metals, are also reactive but less so than alkali metals; their reactivity increases down the group as well. Both groups readily form compounds with nonmetals, but the nature and vigor of their reactions vary significantly.
What is the relationship between an alkali metal and location in group 1A and its reactivity?
Th reactivity of alkali metals increases from the top of Group 1A to the bottom
Among the alkali metals how does the tendency to react with other substances change within a group?
The chemical reactivity increase down in the group.
Differences between alkil metals and halogens?
The elements of the 1st GROUP of the periodic table are called alkali metals. The elements of the 17th GROUP of the periodic table are called halogens. Alkali metals are soft metals whereas halogens are non-metals.
How does the reactivity of group 1 metals change as you go down group 1?
The reactivity increase down in the group.
The Family of what is the most reactive group of metals in the periodic table?
The most reactive group of metals in the periodic table is Group 1, the alkali metals. These metals are highly reactive due to their low ionization energies, which means they readily lose their outermost electron to form positive ions. This reactivity increases as you move down the group due to the decreasing ionization energies.

What groups of metals is the most active?
The alkali metals (Group 1) are the most active metals because they have low ionization energies and readily lose their outer electron to form ions. This reactivity increases as you move down the group due to the decreasing ionization energy.
What are the most reactive elements in the group of akali metals?
The most reactive elements in the group of alkali metals are cesium and francium. They are highly reactive due to their low ionization energy and tendency to lose their outermost electron to achieve a stable electron configuration. Due to their reactivity, they are stored under oil to prevent reaction with moisture in the air.
What are the differences between alkali metals and alkaline earth metals in terms of their properties and reactivity?
Alkali metals and alkaline earth metals are both groups of elements on the periodic table, but they have distinct differences in their properties and reactivity. Alkali metals are located in Group 1 of the periodic table and are highly reactive, soft metals that easily lose their outermost electron to form positive ions. In contrast, alkaline earth metals are located in Group 2 and are less reactive than alkali metals, but still have a tendency to lose electrons to form positive ions. Alkaline earth metals are harder and have higher melting points compared to alkali metals. Overall, alkali metals are more reactive and have lower melting points than alkaline earth metals.
3 How does reactivity change as you go down Group 1 Does the same pattern hold for group 2?
As you go down Group 1 (alkali metals), reactivity increases due to the lower ionization energy, making it easier for these metals to lose their outermost electron. In contrast, Group 2 (alkaline earth metals) also shows an increase in reactivity down the group, but the trend is less pronounced compared to Group 1. This is because while ionization energy decreases, the presence of two outer electrons means that the reactivity is not solely dependent on losing one electron. Overall, both groups exhibit increasing reactivity down the group, but the rate of change is stronger in Group 1.
What is three families from the periodic table?
Three families from the periodic table are the alkali metals (group 1), the halogens (group 17), and the noble gases (group 18). Alkali metals are highly reactive, halogens are nonmetals that are also reactive, and noble gases are inert gases with low reactivity.
