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 smaller than the atomic radius of beryllium?
The atomic radius of beryllium is approximately 112 picometers. Lithium, which has a smaller atomic radius of about 152 picometers, is smaller than beryllium.
Is boron atomicly bigger or smaller than Oxygen?
Boron is atomicly smaller than oxygen. Boron has a smaller atomic radius compared to oxygen due to fewer electrons and a lower atomic number.
What atom has the largest atomic radius calcium iodine potassium or cesium?
Cesium has the largest atomic radius among calcium, iodine, potassium, and cesium. It is located at the bottom of the periodic table in Group 1 (alkali metals), and as you move down a group, atomic radius increases due to additional electron shells.
Why has bromine got a bigger atomic radius than iodine?
Bromine has a larger atomic radius than iodine because it has one more electron shell. As you move down a group in the periodic table, the atomic radius increases due to the addition of energy levels. Bromine, being higher up in the group, has a larger atomic radius than iodine.
Barium element is larger or smaller than caesium?
Barium is smaller than caesium. Different elements have different atomic radii, with caesium having a larger atomic radius compared to barium.
Which has the smallest radius K Rb K Rb?
Rb+ has a smaller radius than K+ due to increased effective nuclear charge in rubidium. Therefore, K+ has a smaller radius than Rb.
How does calcium atomic radius compare to magnesiums radius and potassiums radius?
Calcium has a larger atomic radius than magnesium and a smaller atomic radius than potassium. This trend is due to the increase in number of protons and electrons as you move across the period on the periodic table from magnesium to calcium to potassium.
Is gallium bigger than potassium?
No, gallium is smaller than potassium. In the periodic table, the atomic radius of gallium is less than that of potassium, indicating that gallium's atoms are smaller in size.
Is the atomic radius of potassium larger than of calcium?
Yes, the atomic radius of potassium is larger than that of calcium. This is due to potassium having one more electron shell than calcium, leading to a larger atomic radius.
Which is bigger the atomic radius of potassium or atomic radius of iodine?
The atomic radius of iodine is larger than the atomic radius of potassium. This is because as you move down a group in the periodic table, atomic size increases due to the addition of more electron shells. Iodine is located below potassium in the periodic table, hence it has a larger atomic radius.
How does calcium's atomic radius compared to magnesium radius and potassium radius?
The atomic radius of calcium is larger than magnesium but smaller than potassium. This trend is consistent with the periodic trend across Group 2 elements where atomic radius increases down the group due to additional electron shells. Additionally, going across a period from left to right, atomic radius decreases due to increasing nuclear charge pulling electrons closer.
Which atom has the larger atomic radius K or Li?
K has a larger atomic radius than Li. This is because atomic radius generally increases down a group in the periodic table, so potassium (K) being below lithium (Li) in Group 1 will have a larger atomic radius.
What happens to the atomic radius when an electron is lost?
the positive ionic radius is smaller than the neutral atomic radius
How does its potassium atomic radius compare to that of sodium?
The atomic radius of potassium is larger than that of sodium. This is due to the increase in atomic size as you move down a group in the periodic table, with potassium being located below sodium.
What happens to an atomic radius when an electrons is lost?
The positive ionic radius is smaller than the neutral atomic radius
Does an atom of fluorine have larger or smaller radius than an atom of iodine?
Smaller
What is smaller than the atomic radius of beryllium?
The atomic radius of beryllium is approximately 112 picometers. Lithium, which has a smaller atomic radius of about 152 picometers, is smaller than beryllium.
