Atomic weight of all elements are relative to oxygen atom being taken as 16. The atomic weight of sodium is 6.940. Sodium metal has a density of 0.59. Density is mass per unit volume. Therefore the atomic volume of sodium is 11.763. Assuming atoms and molecules are spheres, the radius is the cube root of 11.763 divided by (pi x 4/3). But, this is relative oxygen, the radius of which in angstrom units has been determined
The only purpose of knowing the radius of an atom is to calculate its atomic or molecular volume, which, in the case of gases is very nearly the same by calculation but maybe universally equal in fact.
The original determination of the atomic weights of the inert gases was the mass of 22.4 litres of each of them. I, personally, determined the atomic weight of iron accurately to 5 decimal places in the chemistry laboratory of my local university, by chemical means. I could have calculated the atomic volume had that have been required.

What is the difference between the atomic radii of sodium (Na) and potassium (K)?
The atomic radius of sodium (Na) is smaller than the atomic radius of potassium (K). Sodium has a smaller atomic radius because it has fewer electron shells compared to potassium.
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.
How does potassiums atomic radius compare to that of sodium?
Potassium has a larger atomic radius compared to sodium. This is because as you move down a group in the periodic table, the atomic radius increases due to the addition of more energy levels. In the case of potassium and sodium, potassium is located below sodium in the same group, resulting in a larger atomic radius for potassium.
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.
How do the atomic radius and metallic properties of sodium compare to the atomic radius and metallic properties of phosphorus?
Sodium has a larger atomic radius and exhibits metallic properties due to its tendency to lose an electron and form positively charged ions. Phosphorus has a smaller atomic radius and tends to gain electrons to achieve a stable electron configuration, making it more likely to exhibit non-metallic properties.

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 does its potassium atomic radius compare to that of sodium?
The atomic radius of potassium is larger than that of sodium. This is due to the increase in atomic size as you move down a group in the periodic table, with potassium being located below sodium.
What has the larger atomic radius sodium or sulfur?
Sodium has a larger atomic radius than sulfur. This is because atomic radius generally decreases as you move from left to right across a period in the periodic table, and sodium is located in the leftmost group while sulfur is farther to the right.
What has the largest radius magnesium silicon sulfur or sodium?
Among magnesium, silicon, sulfur, and sodium, sodium has the largest atomic radius. This is due to its position in the periodic table; sodium is an alkali metal with a larger atomic radius compared to the other elements, which are nonmetals or metalloids. As you move down a group in the periodic table, the atomic radius increases, and sodium is lower in its group than magnesium, silicon, and sulfur. Thus, sodium has the largest radius of the four elements.
What is the largest radius Na or Al?
Sodium has a larger atomic radius than aluminum.
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.
Why is the atomic radius of sulfur is less than sodium?
The atomic radius of sulfur is less than sodium because sulfur has more protons in its nucleus, leading to a stronger attraction to its electrons, making the atomic size smaller. Sodium has fewer protons and a larger atomic radius due to weaker attraction between its nucleus and electrons.
