NA
To order atoms from largest to smallest atomic radius, consider the periodic trends. Generally, atomic radius increases down a group and decreases across a period from left to right. For example, if we compare sodium (Na), magnesium (Mg), and aluminum (Al), the order from largest to smallest atomic radius would be Na, Mg, Al.
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.
Among the elements magnesium (Mg), chlorine (Cl), sulfur (S), and sodium (Na), sodium (Na) is the largest in terms of atomic radius. Atomic size generally increases down a group in the periodic table and decreases across a period. Sodium, being in Group 1 and having a lower atomic number than chlorine, has a larger atomic radius. Thus, Na is the largest of the elements listed.
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.
Sodium has a larger atomic radius than aluminum.

The neutral atom of potassium has the largest radius.
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.
Mg has a larger atomic radius than Na. This is because atomic radius generally increases as you move down a group in the periodic table, and Mg is below Na in the same group. Additionally, Mg has more energy levels and electrons compared to Na, contributing to its larger atomic radius.
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.
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.
The atomic radius generally decreases across a period from left to right and increases down a group in the periodic table. Therefore, a sequence arranged in order of decreasing atomic radius might include elements like cesium (Cs), rubidium (Rb), and potassium (K). In this case, Cs would have the largest atomic radius, followed by Rb, and then K, illustrating the trend of increasing size down the group. Another example could be sodium (Na), magnesium (Mg), and aluminum (Al), where Na has the largest radius and Al the smallest.
