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 else can I help you with?
Which of these elements is the smallest element sodium potassium rubidium or cesium?
Of the Group 1 elements stated (Na, K, Rb, Cs), Caesium is the largest as it is the furthest down the group, and Sodium is the smallest of those as it is furthest up the group.
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.
The atomic radius of potassium is smaller than the atomic radius of?
Rubidium; the next higher atomic numbered element in the same column of the periodic table always has a higher atomic radius, with some exceptions among transition elements due to the "lanthanide contraction". However, potassium and rubidium are not transition elements.
What is a period 5 element that reacts explosively with water?
Potassium, which is a period 5 element, reacts explosively with water. When potassium comes into contact with water, it produces hydrogen gas, which ignites immediately due to the heat produced by the reaction, resulting in a small explosion.
Which element has a lower first ionization energy than element S?
Element P (phosphorus) has a lower first ionization energy than element S (sulfur).
Which element between lithium potassium rubidium and cesium has the smallest ionization energy?
T he smallest first ionization energyis for lithium.
Which element has the smallest first ionization energy Na K Rb Li?
The element with the smallest first ionization energy is Francium, as it is located in Group 1 of the periodic table and has the largest atomic size. Among the elements listed, lithium (Li) would have the smallest first ionization energy as it is closer to the upper right of the periodic table compared to sodium (Na), potassium (K), and rubidium (Rb).
What element has a lower ionization energy than Na?
Potassium (K) has a lower ionization energy than sodium (Na).
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 in the second period has the greatest ionization energy?
Neon
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.
What elements has the lowest ionization energy element Rb Na C or F?
Element Rb (Rubidium) has the lowest ionization energy among Rb, Na, C, and F. This is because as you move down a group on the periodic table, the ionization energy typically decreases due to the increase in atomic size. Rubidium is located below sodium (Na) in the same group, so it has a lower ionization energy.
What is the full electron configuration of the period 3 element with the successive ionization energies in potassium?
The full electron configuration of the period 3 element with the successive ionization energies in potassium is 1s2 2s2 2p6 3s2 3p6 4s1.
Is rubidium a transition element?
NO!!!! It is a Group '1' metal, and reacts similarly , but more violently than sodium or potassium.
What period is the element rb in the periodic table?
Rb is the symbol for the element, rubidium.
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
