They all react, but Cesium would be the most reactive, since francium is radioactive we don't consider francium the most reactive.
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.
Period 1: 2 elements Period 2: 8 elements Period 3: 8 elements Period 4: 18 elements Period 5: 18 elements Period 6: 32 elements Period 7: 25 elements
The elements from the group 12 are not the most reactive chemical elements.
The alkali and alkaline earth metals are the least electro negative elements, and the halogens are the most electro negative elements.
Group 1 elements are more reactive than that of group 2 elements.
less reactive.beacuse group-1 elements are the most reactive elements.
the metal potassium and the nonmetal bromine
it is caesium.
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.
Group 1 elements are the most reactive among metals, followed by group 2 elements.
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.
Noble gasses are least reactive of all the elements. So the least reactive element in the period 4 is Krypton. It is a noble gas with an atomic number of 36.
