BeauCesium has a larger atomic radius than sodium. This is because as you move down a group in the Periodic Table, the atomic radius generally increases due to the addition of more energy levels and shielding effect.
Na, or sodium has a larger radius than Li. This is because according to the general trend in Atomic Radius, we normally view that if in a group going from up to down the element has more shells of electrons, hence the distance from the nucleus increases and thus the atomic radius increases. ALSO in the trend of the atomic radius when reading across in a period the principle of quantum number does not change, thus electrons shielding does not change. So as the elements contain another proton the nuclear charge increases, so the electrons are pulled closer to the nucleus, and SO the atomic radii decreases.
Cesium has a larger atomic radius than sodium. This is because Cesium has 6 shells (energy levels) whereas sodium has only 3 shells. Despite the fact that Cesium has more protons in the nucleus, the attraction of the outermost electrons is no sufficient to reduce the atomic radius significantly. There exists a shielding effect.

Does francium or sodium have the smaller atomic radius?
Francium has a larger atomic radius than sodium. Francium is located in the last group of the periodic table, so it has more electron shells than sodium, which results in a larger atomic radius.
Why does sodium have a larger atomic radius than aluminum?
Sodium has a larger atomic radius than aluminum because as you move down a group in the periodic table, the atomic radius increases due to the addition of energy levels. Sodium is located in the third period, while aluminum is in the second period, so sodium has more energy levels and a larger atomic radius.
Does Sodium have a larger atomic radius than Aluminum?
No, aluminum has a larger atomic radius than sodium. Aluminum has a greater number of protons in its nucleus compared to sodium, leading to a larger effective nuclear charge that pulls its electrons closer, resulting in a smaller atomic radius.
Which element has a larger atomic radius than aluminum AL?
Sodium (Na) has a larger atomic radius than aluminum (Al).
Why does rubidium have a larger atomic radius than sodium?
Rubidium has a larger atomic radius than sodium because rubidium has more electrons and energy levels, leading to increased electron-electron repulsion and a larger atomic size. Additionally, the outermost electron in rubidium is in a higher energy level compared to sodium, contributing to a larger atomic radius.
