Which element is the largest Li K Cs?

Of the elements listed by atomic symbol, Cs has the largest atoms.


Does potassium has a higher ionization energy than cesium?

No, cesium has a lower ionization energy than potassium. This is because cesium has a larger atomic size and a weaker attraction between the nucleus and the outermost electron compared to potassium.


Of the following elements which one would have the largest ionization energy Hydrogen (H atomic 1) Cesium (Cs atomic 55) Sodium (Na atomic 11) Potassium (K atomic 19)?

Cesium (Cs) would have the largest ionization energy because it is the element with the highest atomic number in the list. As you move across a period from left to right, the ionization energy generally increases due to increasing effective nuclear charge. Therefore, Cesium would have the highest ionization energy followed by Potassium, Sodium, and then Hydrogen.


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.


What element has the larger first ionization energy cesium or potassium?

Cesium has a larger first ionization energy compared to potassium. This is because cesium is located further down the periodic table in the alkali metal group, meaning it has a larger atomic radius and a lower effective nuclear charge, both of which make it easier to remove an electron from potassium than from cesium.


What is the atomic radius of caesium?

The farther to the left and toward the bottom of the periodic table, the lower the electronegativity, and the larger the atomic radius. Calcium has a large atomic radius in comparison to elements in it's own period. What are you comparing calcium too? Calcium does have a large radius but not the largest, the largest is Cesium.


Which element has the smallest atomic radius rubidium cesium and francium?

Francium has the largest atomic radius among rubidium, cesium, and francium, as atomic radius generally increases down a group in the periodic table.


What are some reactivity?

lithium, sodium, potassium, rubidium, cesium, francium, beryllium, magnesium, calcium, strontium, barium, radium


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.


What are the members of the alkali family?

Lithium, Sodium, Potassium, Rubidium, Cesium, Francium, Beryllium, Magnesium, Calcium, Strontium, Barium, and Radium.


What is the atomic radius for cesium?

Cesium (Cs) has an atomic radius of 265 picometers.


Which element has the largest atomic radius?

Atoms of the element cesium (also caesium), symbol Cs, element number 55.
