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.
What else can I help you with?
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 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?
Se < O < K < Cs - Atomic radius decreases across a period from left to right on the periodic table, while it increases down a group. Therefore, Se has the smallest atomic radius, followed by O, then K, and Cs has the largest atomic radius.
Which ion in the compound K and Br is larger?
The Br ion is larger than the K ion. This is because the Br ion has more electron shells than the K ion, leading to a larger atomic radius.
Does Cs have larger atoms than Li?
Yes because Cs has more Electrons- which causes it to have more shells and this causes the structure to be larger. Li is small because it had a smaller amount of electrons- so it doesn't need a lot of shells which causes the shell to be smaller and the valence electron to be closer to the nucleus.
Which element is the largest Li K Cs?
Of the elements listed by atomic symbol, Cs has the largest atoms.
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 has the greatest radius Cs Fr K Li?
Francium (Fr) down a group, the radius increases.
Does na1 have a larger atomic radius than k1?
K+ has larger radius
How would you rank these atoms from smallest to largest atomic radius Cs K O Se?
Se < O < K < Cs - Atomic radius decreases across a period from left to right on the periodic table, while it increases down a group. Therefore, Se has the smallest atomic radius, followed by O, then K, and Cs has the largest atomic radius.
Which is larger Cs or Be?
Caesium (260 pm) has a larger covalent atomic radius than beryllium (105 pm).
What elements have a smaller atomic radius than strontium?
Ca, Mg, Be, Fr, Cs, Rb, K, Na, Li, H
Which ion in the compound K and Br is larger?
The Br ion is larger than the K ion. This is because the Br ion has more electron shells than the K ion, leading to a larger atomic radius.
Does Cs have larger atoms than Li?
Yes because Cs has more Electrons- which causes it to have more shells and this causes the structure to be larger. Li is small because it had a smaller amount of electrons- so it doesn't need a lot of shells which causes the shell to be smaller and the valence electron to be closer to the nucleus.
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.
How many F atoms are needed to occupy the same volume as a Cs atom?
Since the volume of an atom is determined by the radius of its electron cloud, we can use the atomic radius to approximate the volume each atom occupies. The atomic radius of Cs is larger than that of F, so more F atoms would be needed to occupy the same volume as one Cs atom. Approximately 9 F atoms are needed to occupy the same volume as one Cs atom.
What is the atomic radius for cesium?
Cesium (Cs) has an atomic radius of 265 picometers.
