Caesium's single outer electron is much further from the nucleus than that of sodium, so caesium loses its valence electron much easily than sodium, therefore caseium is much more reactive than sodium.

it is about Caesium metal. it is reactive than others.


Caesium is the 5th element in group I of the periodic table. It is an alkali metal, and they become more reactive as you go down the group from lithium to sodium to potassium etc. So we would expect that caesium is highly reactive, even more reactive than rubidium.


The electronegativity of caesium is higher.


Caesium is slightly more reactive than barium.


Francium is considered to be more reactive than caesium.



sodium is more reactive than magnesium!


No! sodium is more reactive.


No it is not true. sodium is more reactive than mg.


Sodium is more reactive than sulfur.


sodium is more reactive than chlorine


Sodium is more reactive than magnesium.


The rubidium Pauling electronegativity is 0,82 and the caesium Pauling electronegativity is 0,79; so caesium is more reactive but the difference is not significant.


Lithium is not more reactive than sodium and potassium.


No, titanium is less reactive than sodium.


No, calcium is less reactive than sodium.



Sodium is more reactive than Lithium because the metals of Group 1 become more reactive as we go down the group. The ionization energy of lithium is greater than the ionization energy of sodium, and thus sodium is more reactive.


The ionization energy of lithium is a bit greater than the ionization energy of sodium. Sodium is more reactive.


Francium is more reactive than sodium.


I think sodium is more reactive than copper, because on the Reactivity Series list sodium is higher than copper.


Potassium is more reactive than sodium


The ionization energy of lithium is greater than the ionization energy of sodium, and soium is consequently more reactive.


Francium is the most reactive with water and it's radio active. The Caesium water explosions are also quite violent, but it all comes down to what you react it with.


The electronegativity of sodium is lower.
