Cs has a lower ionisation energy than Na.
Cs has more electrons (44 more electron) than Na. The electrons in the outer electronshell are further away from the positive nucleus because there are many more electron shells.
Because the valence electrons are further from the nucleus they are not held as tightly by the atom, this means that it takes less energy to remove the electron in the outer electron shell from Cs.
So it is more reactive.
What else can I help you with?
What element is more reactive than lithium and magnesium but less ractive than pottassium?
Sodium is more reactive than lithium and magnesium but less reactive than potassium.
Is Cesium or Potassium more reactive in water?
Potassium is more reactive in water compared to cesium. When potassium reacts with water, it produces hydrogen gas and heat at a faster rate than when cesium reacts with water.
Why is cesium chloride less reactive than cesium?
The high reactivity of cesium comes from its tendency to give up the one electron in its outermost shell and become a cesium 1+ ion, which is more stable. In cesium chloride, the cesium is already in its stable ionic form.
What weighs more magnesium or white ash?
Magnesium weight more than ash. White ash is magnesium oxide.
What weighs more magnesium or the white ash?
Magnesium weight more than ash. White ash is magnesium oxide.
What element is more reactive than lithium and magnesium but less ractive than pottassium?
Sodium is more reactive than lithium and magnesium but less reactive than potassium.
Which element will have a larger atomic radius magnesium or cesium?
Cesium will have a larger atomic radius than magnesium. This is because atomic radius tends to increase down a group in the periodic table, and cesium is located below magnesium in the periodic table.
Is Magnesium Cesium an ionic compound?
No, magnesium cesium is not an ionic compound. Ionic compounds are formed when a metal and a nonmetal react and transfer electrons to each other to create charged ions. Magnesium and cesium are both metals, so they cannot form an ionic compound together.
What is an element more metallic than cesium?
Francium is more metallic than cesium. It is an alkali metal located below cesium in the periodic table and is the most reactive metal known.
Is Cesium or Potassium more reactive in water?
Potassium is more reactive in water compared to cesium. When potassium reacts with water, it produces hydrogen gas and heat at a faster rate than when cesium reacts with water.
Is sulfur more electronegative than cesium?
Yes, sulfur is more electronegative than cesium. Sulfur has an electronegativity value of 2.58 on the Pauling scale, while cesium has an electronegativity value of 0.79. This means that sulfur has a stronger ability to attract electrons in a chemical bond compared to cesium.
Is Sodium is more reactive than magnesium.?
sodium is more reactive than magnesium!
Would francium combine with water more or less readily than cesium?
Francium would combine with water more readily than cesium. Francium is the most reactive alkali metal due to its position in the periodic table, so it would react more violently with water compared to cesium.
Why is cesium chloride less reactive than cesium?
The high reactivity of cesium comes from its tendency to give up the one electron in its outermost shell and become a cesium 1+ ion, which is more stable. In cesium chloride, the cesium is already in its stable ionic form.
Is magnesium more reactive than sodium?
sodium is more reactive than magnesium!
Would you expect cesium to be more or less reactive than potassium?
AnswerDespite the fact that you could look it up that cesium is indeed more reactive than potassium, you could also take into account the periodic trends. One of these trends is that metals tend to be more reactive as you proceed down a group/family and as you move to the left of the table. Since both cesium and sodium are members of the alkali metals, cesium should be more reactive of the two.
Why is cesium more reactive than sodium?
because it is less stable
