Which is more soluble in water among lithium and cesium?
Lithium and cesium are both highly reactive metals that will react violently with water (forming a hydroxide compound and giving off hydrogen gas) so the question of relative solubility doesn't really arise.
Which atom lithium or cesium needs more energy to become an ion?
Cesium needs more energy to become an ion than lithium because cesium has a higher ionization energy due to its larger atomic size and greater distance of valence electrons from the nucleus. This makes it more difficult to remove electrons from cesium compared to lithium.
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 conductivity of lithium is less than cesium?
The conductivity of lithium is less than cesium because lithium has smaller atomic size and higher ionization energy compared to cesium. This results in weaker metallic bonding and less mobile charge carriers in the lattice structure of lithium, leading to lower conductivity. Additionally, lithium also has a higher tendency to form covalent bonds, which further reduces its conductivity.
How does lithium burn in hydrochloric acid?
Lithium reacts with hydrochloric acid to produce lithium chloride and hydrogen gas. The reaction is exothermic and vigorous, with the hydrogen gas being evolved as bubbles. The lithium chloride formed remains dissolved in the solution.
Which one is the most reactive metal potassium lithium or sodium?
Potassium is the most reactive of the three metals (potassium, lithium, and sodium). It reacts vigorously with water, producing hydrogen gas and heat. Sodium is less reactive than potassium, while lithium is the least reactive among the three.
What Group 1A elements is the most reactive cesium potassium lithium or sodium?
Cesium is the most reactive Group 1A element because it has the lowest ionization energy and the largest atomic radius, making it more willing to donate its outermost electron in a chemical reaction compared to potassium, lithium, and sodium.
Do elements in the same group have the same reactivites?
Elements in the same group usually have similar, but not the same, reactivity. For example, the noble gases are generally inert, but helium and neon are more inert than argon and krypton, which form a limited number of compounds. Additionally, the alkali metals all react in a similar manner with water, but the reaction of lithium with water is much less vigorous than the reaction of cesium with water.
Why is cesium more reactive than lithium?
Both cesium and lithium react by giving up the single electron int their outer shells. Cesium has a larger atomic radius than lithium does and more electron shells between the nucleus and the outer shell. As a result, cesium's valence electron is less attracted to the nucleus than Lithium's is and is therefore more easily removed.
What is the difference between cesium and lithium?
Interestingly, ceasium and lithium are both made of the same fundamental particles and cannot be easily distinguished. The only known test for distinguishing these elements is to drop them in water. Lithium will release a satisfactory whistling noise 3 cents below middle C (at STP). Ceasium will only be 2 cents flat. If you have a chunk of lithium contaminated with ceasium (and you have a good ear) it will sound irritatingly out of tune.
Which element is more reactive lithium or cesium?
i have the same question too! im googling all my questions now a days...idk either!
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.
