The reactivity increase down in the group.
Metallic character decreases from left to right. Electronegativity increases.
Metals Period - reactivity decreases as you go from left to right across a period.Group - reactivity increases as you go down a group Why? The farther to the left and down the periodic chart you go, the easier it is for electrons to be given or taken away, resulting in higher reactivity.Non-metals Period - reactivity increases as you go from the left to the right across a period.Group - reactivity decreases as you go down the group. Why? The farther right and up you go on the periodic table, the higher the electronegativity, resulting in a more vigorous exchange of electron.
The chemical reactivity increase down in the group.
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.
The reactivity of alkali metals increases as you move down Group 1 from lithium to francium. This trend is due to the decreasing ionization energy, which makes it easier for the alkali metals to lose their outermost electron and become more reactive.
Th reactivity of alkali metals increases from the top of Group 1A to the bottom
Reactivity generally increases down a group of atoms. This is because as you move down the group, the atomic radius increases and the valence electrons become further from the nucleus. As a result, the valence electrons are less strongly attracted to the nucleus, making them more easily available for bond formation and chemical reactions.
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.
