Which has a larger atomic radius sodium or cesium?

Answer 1

No.

Lithium and sodium are both from the same column of the periodic table and so have similar chemical properties. Lithium is atomic number 3 with a weight of 6.94. Sodium is much bigger and heavier with an atomic number of 11 and a weight of 22.99.

Answer 2

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.

Answer 3

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.

Answer 4

Na is larger because it has more electron shells than Li.

Answer 5

Sodium.

Because, down a group the radius increases as the number of shells / orbitals increases.

Answer 6

A sodium (Na) atom has a slightly larger atomic radius than a lithium (Li) atom. Their atomic radii are about 2.23 and 2.05 angstroms, respectively.

Answer 7

Sodium has a larger atomic radius than lithium because it has one more electron shell than sodium does.

Answer 8

Sodium has a larger atomic radius (empirical).

Answer 9

Na has larfer radius. Since it has more shells as compared to Li.

Answer 10

Na has a larger atomic radius than Li.
