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.

Out of sodium potassium rubidium and cesium Which element has the greatest ionization energy?
Sodium has the greatest ionization energy of the four elements listed from column 1 of a wide form periodic table. Among this group of metals that readily form cations, the largest always has the lowest ionization energy and the smallest has the most. This is generally ascribed to the fact that the valence shell electron is further from the nucleus in the largest element and nearest in the smallest element.
Which is greater the second ionization energy of potassium or that of calcium?
The second ionization energy of calcium is greater than that of potassium. This is because calcium, with its higher nuclear charge and smaller atomic size compared to potassium, holds onto its electrons more tightly.
Which element has a lower first ionization energy than element S?
Element P (phosphorus) has a lower first ionization energy than element S (sulfur).
Does potassium or bromine have a higher ionization energy?
Bromine has a higher ionization energy than potassium. This is because bromine's electrons are held more tightly due to its higher nuclear charge and smaller atomic size compared to potassium.
Which element has a higher first ionization energy than chlorine Cl?
The element with a higher first ionization energy than chlorine Cl is fluorine F. Fluorine is located to the left of chlorine in the periodic table, which means it has a smaller atomic radius and stronger nuclear attraction, requiring more energy to remove an electron.
Which element between lithium potassium rubidium and cesium has the smallest ionization energy?
T he smallest first ionization energyis for lithium.
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.
Out of sodium potassium rubidium and cesium Which element has the greatest ionization energy?
Sodium has the greatest ionization energy of the four elements listed from column 1 of a wide form periodic table. Among this group of metals that readily form cations, the largest always has the lowest ionization energy and the smallest has the most. This is generally ascribed to the fact that the valence shell electron is further from the nucleus in the largest element and nearest in the smallest element.
What is ionization energy and which element has the lowest ionization energy?
Ionization energy is the energy required to remove an electron from an atom in the gaseous state. Francium has the lowest ionization energy among elements.
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 element has a lower ionization energy than Na?
Potassium (K) has a lower ionization energy than sodium (Na).
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.
Which element has a low ionization energy?
Potassium has a low ionization energy due to its large atomic size and one electron in its outermost shell, making it easier to remove that electron.
Which element has a first ionization of 418kJmol?
The element with a first ionization energy of 418 kJ/mol is strontium (Sr). Strontium is a metallic element in Group 2 of the periodic table, and its first ionization energy corresponds to the energy required to remove one electron from a neutral strontium atom to form a +1 ion.
Which element has a lower first ionization energy than aluminum?
As an example potassium has a lower first ionization energy than aluminum (Al).
What element in family IA has the lowest ionization energy?
the lowest ionization energy in IA :hydrogen ,lithiun ,sodium and potassium
Does potassium have a high or low ionization energy?
Potassium has a low ionization energy.
