Sodium has a larger atomic radius and is more metallic.
yes
Sodium has a larger atomic radius than aluminum.
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.
a larger nuclear charge

yes
Sodium has a larger atomic radius than aluminum.
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.
No. A cesium atom is larger both in terms of atomic mass and atomic radius.

For the representative elements (main group elements), atomic radius generally decreases from left to right across a period. Example: B and Fl: Fl has the smaller atomic radius Li and Be: Be has the smaller atomic radius
a larger nuclear charge
Hydrogen has the smallest atomic radius - 25 pm.
the atomic radius of sodium is greater than of gold.
The atomic radius of potassium is greater than that of sodium. Therefore, the single valence electron that exists for all alkali metals is located farther from the nucleus for potassium than sodium. This results in less energy required to remove that valence electron from potassium than from sodium, leading to increased reactivity. Note that this trend continues as you move down Group I on the Periodic Table, meaning that Rubidium is more reactive than Potassium and Cesium is more reactive than Rubidium.
Sodium Atom has a larger atomic radius than chlorine, because as we go across the period the nuclear charge (charge on the atom) increases, also outermost electrons occupy the same principle energy level as we go across the period(3 sub energy level) so the electrons in chlorine are held more closely and tightly together than that of sodium....so sodium has a larger atomic radius
