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 else can I help you with?
What do the reactivity of metals in group 1 and 2 generally increase with?
The reactivity of metals in groups 1 and 2 generally increases as you move down the group. This is due to the increasing ease with which the outermost electron can be lost to form positive ions.
How does reactivity change from top to bottom in group1 does the same pattern hold in group2?
Reactivity generally increases from top to bottom in Group 1 elements due to the decrease in ionization energy. In contrast, Group 2 elements do not show the same reactivity trend as Group 1; reactivity generally increases from top to bottom due to the decreasing ionization energy, but other factors such as atomic size and electron shielding can also influence the reactivity patterns in Group 2.
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.
Does the reactivity of elements in group 2 increase going up or down?
The reactivity is increasing goinng down in the group.
What is the reactivity of group 7?
The reactivity of group 17 elements differ as you move down the periods. Group 17 elements are missing 1 electron from their valance shell making them highly votile and reactive.I'll try not to make this confusing:1. As elements get bigger, they have a higher level of reactivity. (More "pull" needed from protons in the nucleus in order to keep valance shell electrons in orbit).2. As you move from left to right in the groups, you have a higher level of reactivity.3. Groups 1 and 17 have the highest levels of reactivity (except hydrogen in group 1) because they are away by only 1 valence electron.
How does the reactivity of group 1 metals change as you go down group 1?
The reactivity increase down in the group.
What do the reactivity of metals in group 1 and 2 generally increase with?
The reactivity of metals in groups 1 and 2 generally increases as you move down the group. This is due to the increasing ease with which the outermost electron can be lost to form positive ions.

What two groups of the periodic table are most similar in chemical properties?
The alkali metals (Group 1) and the alkaline earth metals (Group 2) are most similar in chemical properties due to both groups having similar metallic properties, reactivity, and ability to form cations with a +1 or +2 charge.
What happens to the reactivity as you move down group 1 in the periodic table?
Reactivity in group 1 of elements increases as we go down the group (to francium) because in the alkali metals as we go down the group number of atomic shells increases so the elements with most shells will easily release their electrons in the outer most shell.
Which element would you expect to be the most reactive in group 1 and group 2?
In Group 1, cesium (Cs) is expected to be the most reactive element, as reactivity increases down the group due to the increasing atomic radius and the decreasing ionization energy. In Group 2, barium (Ba) is typically the most reactive, as reactivity also increases down this group for similar reasons—larger atomic size and lower ionization energy. Both cesium and barium readily lose their outermost electrons, making them highly reactive.
What is the pattern of outer shell electrons in a group?
In a group, elements have the same number of outer shell electrons, which corresponds to the group number. For example, elements in Group 1 have 1 outer shell electron, elements in Group 2 have 2 outer shell electrons, and so on. This pattern helps determine the reactivity and chemical properties of elements within the same group.
Are transition metals on the periodic table reactive?
Transition metals tend to be less reactive than alkali metals or alkaline earth metals. They often form colorful compounds, have multiple oxidation states, and can act as catalysts in chemical reactions. However, some transition metals can still react with certain elements or compounds under the right conditions.
Is Ga or Se less reactive?
Ga has a nfpa code of 1 on reactivity and Se has a reactivity of 2.
