They all react, but Cesium would be the most reactive, since francium is radioactive we don't consider francium the most reactive.
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.
Group 1 elements are more reactive than that of group 2 elements.
Except hydrogen, elements in group 1 are very reactive at they can give away their only electron in their valence shell easily to be ionized.
No, period 1 elements are not more electronegative than period 2 elements. Electronegativity generally increases across a period from left to right, so elements in period 2 are generally more electronegative than elements in period 1.
The reactive elements on the periodic table are typically found in groups 1 and 2 (for example, alkali metals like sodium and potassium) and groups 16 and 17 (for example, halogens like chlorine and fluorine). These elements are reactive because they readily form compounds with other elements to achieve a stable electron configuration.
The alkali and alkaline earth metals are the least electro negative elements, and the halogens are the most electro negative elements.

less reactive.beacuse group-1 elements are the most reactive elements.
the metal potassium and the nonmetal bromine
it is caesium.
Group 1 elements are the most reactive among metals, followed by group 2 elements.
Elements at the center of a period tend to have the highest electronegativity and smallest atomic radii compared to the other elements in the period. Additionally, these elements often possess a stable electron configuration.
they become more reactive since you are moving from left to right on the Periodic Table, the elements in group 17 are the most reactive.
S block has the most reactive elements. The groups 1 and 2 belongs to the s block.
they become more reactive since you are moving from left to right on the Periodic Table, the elements in group 17 are the most reactive.
Except hydrogen, elements in group 1 are very reactive at they can give away their only electron in their valence shell easily to be ionized.
