Sodium has a larger atomic radius than aluminum.
Potassium has the largest atomic radius.
Sodium (Na) has a larger atomic radius than aluminum (Al).
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.
The smallest atomic radius is found in Cl (Chlorine), followed by Al (Aluminum), then Na (Sodium), and finally Mg (Magnesium). The trend typically follows an increase in atomic radius from right to left across a period and from top to bottom down a group on the periodic table.
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.
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.
The neutral atom of potassium has the largest radius.
Potassium has the largest atomic radius.
Sodium (Na) has a larger atomic radius than aluminum (Al).

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 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.
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.
Ti
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.
From the given elements, potassium has the largest atomic radius.
