Cesium has the larger atomic radius, because it has electrons in 6 energy levels, whereas potassium has electrons in only 4 energy levels. As a result, cesium is the more reactive of these two alkali metals, because its valence electron is farther away from the nucleus, and thus easier to manipulate away from that atom to form an ion.

Which atom has the larger atomic radius K or Li?
K (potassium) has the larger atomic radius.
What has the greatest radius Cs Fr K Li?
Francium (Fr) down a group, the radius increases.
How would you rank these atoms from smallest to largest atomic radius Cs K O Se?
The order is: O (60 pm), Se (115 pm), K (220 pm), Cs (260 pm); these are covalent radii after Slater.
What group of elements have members of the smallest atomic radii for a given period?
Noble gases have the smallest atomic radius.
Rank these elements in terms of increasing atomic radius?
In terms of atomic radius, the sequence would be oxygen, carbon (both period 2), magnesium (period 3), rubidium (period 4), and cesium (period 5). Note that order by periods is not absolute: in each period, the elements toward the far left side have the largest radii. For example, the radius for lithium in period 2 is larger than almost all of the elements in periods 3 and 4. *Numerically, the elements O, C, Mg, Rb, and Cs have respective radii of about 60, 70, 150, 235, and 260 picometers.
Which atom has the larger atomic radius K or Li?
K (potassium) has the larger atomic radius.
Does na1 have a larger atomic radius than k1?
K+ has larger radius
What has the greatest radius Cs Fr K Li?
Francium (Fr) down a group, the radius increases.
Which is larger Cs or Be?
Caesium (260 pm) has a larger covalent atomic radius than beryllium (105 pm).
How would you rank these atoms from smallest to largest atomic radius Cs K O Se?
The order is: O (60 pm), Se (115 pm), K (220 pm), Cs (260 pm); these are covalent radii after Slater.
What elements have a smaller atomic radius than strontium?
Ca, Mg, Be, Fr, Cs, Rb, K, Na, Li, H
What has the largest radius K or Na?
Postassium, K, has a larger radius than sodium, Na, because it is in the next period on the table but in the same group as sodium.
What is the atomic radius for cesium?
Cesium (Cs) has an atomic radius of 265 picometers.
How does the presence of core electrons affect the atomic radius of elements?
When there is an anion (negative charge) the radius will be larger because it is more full whereas it will be smaller if it is a positive charge because of less electrons. ex largest to smallest radius (K-,K, K+)
Which element is the largest K Rb Na Li?
Rb is the largest, Li the smallest in the row above. Group 1 of the periodic table: Fr > Cs > Rb > K > Na > Li > H
What group of elements have members of the smallest atomic radii for a given period?
Noble gases have the smallest atomic radius.
When does a wheel and axle have a mechanical advantage greater than one?
When the radius of the wheel is larger than the radius of the axle - which is almost always true.When the radius of the wheel is larger than the radius of the axle - which is almost always true.When the radius of the wheel is larger than the radius of the axle - which is almost always true.When the radius of the wheel is larger than the radius of the axle - which is almost always true.
