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 else can I help you with?
What is smaller than the atomic radius of beryllium?
Generally, any element with a lower atomic number.
Is boron atomicly bigger or smaller than Oxygen?
Boron has a larger atomic radius but a smaller atomic mass.
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 SMALLER atomic radius because it has one more electron shell than Iodine. On the periodic table, atomic radius of an atom decreases across a period and increases down a group. Since Bromine and Iodine are in the same group, you know Bromine has a smaller atomic radius because it is in a lower period.
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.
What is the difference between the atomic radii of sodium (Na) and potassium (K)?
The atomic radius of sodium (Na) is smaller than the atomic radius of potassium (K). Sodium has a smaller atomic radius because it has fewer electron shells compared to potassium.
Which has the smallest radius K Rb K Rb?
Potassium's atomic radius is smaller than rubidium's because potassium has fewer energy levels of electrons.
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?
if i remember correctly, the element which has the biggest atomic number is the biggest.
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
