Look at your Periodic Table and you will see that K, potassium, must have the largest radius of these choices.
You know that, K + and Na + will be small in radius because they have donated an electron to become positively charged cations.
The neutral atom of potassium has the largest radius.
Na+ is smaller than Na.
Na has a larger atomic radius than Br. This is because Na is a metal and atoms in metals have larger atomic radii compared to nonmetals like Br, which has a smaller atomic radius due to its higher effective nuclear charge.
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.
Na atom has a higher atomic radius compared to Na+ ion. This is because Na+ ion has lost an electron, leading to a decrease in electron-electron repulsion and a smaller electron cloud, causing the ion to have a smaller atomic radius than the neutral Na atom.
The neutral atom of potassium has the largest radius.
Potassium has the largest atomic radius.
Na+ is smaller than Na.
Sodium has a larger atomic radius than aluminum.
Na has a larger atomic radius than Br. This is because Na is a metal and atoms in metals have larger atomic radii compared to nonmetals like Br, which has a smaller atomic radius due to its higher effective nuclear charge.
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.
Na atom has a higher atomic radius compared to Na+ ion. This is because Na+ ion has lost an electron, leading to a decrease in electron-electron repulsion and a smaller electron cloud, causing the ion to have a smaller atomic radius than the neutral Na atom.

Sodium (Na) is the largest element among Mg (magnesium), S (sulfur), Na (sodium), and Cl (chlorine) when comparing their atomic radii. Sodium has the largest atomic radius because it is located in the third period of the periodic table, whereas magnesium is smaller due to being in the second period.
K (potassium) would have the largest atomic radius out of the elements given because it is located in the lower left corner of the periodic table. As you move down a group in the periodic table, the atomic radius increases due to the addition of more electron shells.
Rb (rubidium) is the largest element among K (potassium), Rb (rubidium), Na (sodium), and Li (lithium). This is because as you move down a group in the periodic table, the atomic size increases due to the addition of more electron shells.
Sodium(Na) has smaller radius than Bromine because Na has less number of shells.
