What else can I help you with?
Where are the metals and nonmetals located on the peridoic table?
Metals are located on the left side of the periodic table, while nonmetals are located on the right side. There is a diagonal line dividing the metals and nonmetals, with metalloids lying along this line.
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.
Which group of nonmetals are most reactive?
The halogens are the most reactive group of nonmetals. This group includes elements like fluorine, chlorine, bromine, and iodine, which readily react with other elements to form compounds. They have high electronegativity and tend to gain electrons in chemical reactions.
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.
How do the ionic radii vary within a group of metals how do they vary within a group of nonmetals?
Within a group of metals, the ionic radii generally increase as you move down the group due to the addition of higher energy levels. Within a group of nonmetals, the ionic radii also increase as you move down the group due to the addition of higher energy levels, but they are typically smaller compared to metal ions of the same period.
How does the reactivity of group 1 metals change as you go down group 1?
The reactivity increase down in the group.
How does reactivity work with the elements going down the groups for metals and non metals?
For metals, reactivity generally decreases as you move down a group because the outer electrons are further from the nucleus, making it harder for them to be lost. Nonmetals tend to become more reactive as you move down a group because they have more energy levels and an increased ability to gain electrons. Overall, the reactivity of elements going down a group is influenced by changes in atomic size and electron affinity.
Where are the metals and nonmetals located on the peridoic table?
Metals are located on the left side of the periodic table, while nonmetals are located on the right side. There is a diagonal line dividing the metals and nonmetals, with metalloids lying along this line.
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.
Where and what side on the periodic table is more active?

What are the three major categories the elements are broken down into in the Periodic Table?
The three major categories in the Periodic Table are metals, nonmetals, and metalloids. Metals are typically shiny, malleable, and good conductors of heat and electricity. Nonmetals are often dull in appearance and poor conductors of heat and electricity. Metalloids have properties that are intermediate between metals and nonmetals.
Where are metals located on the periodic chart?
The more left and the more down in the periodic table, you'll find the metals (except hydrogen). Only in the upper right corner (at fluorine) are the nonmetals. On the mid-diagonal in between both corners there is the greatest group containg the metalloids (half metals). But excluded from all this, is the 'noble gas'-group.
Why some metals are found in the group with nonmetals?
With the ecception of th ehalogens, group 17, the groups that have non-metals as the lightest groups 13, 14, 15, 16, the metallic character of the elements generally increaes as you go "down" the group, as the atomic number increases. As you go down a group the ionization potentials drop, it becomes progressivly easier for the electrons to be removed. This is one of the prerequisites for a metallic bond where the s and p electrons are "free to roam". the more obvious concluion is that the formation of cations gets easier which is characteristic of metals.
Which group of elements form cations?
what are true about cationA.Metals are not likely to form cations.B.Cations are always smaller than the neutral form of the element.C.Cation size decreases as you go down a group.D.All cations are larger than any anion.E.Cations cannot form in nature.
Which group of nonmetals are most reactive?
The halogens are the most reactive group of nonmetals. This group includes elements like fluorine, chlorine, bromine, and iodine, which readily react with other elements to form compounds. They have high electronegativity and tend to gain electrons in chemical reactions.
