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.
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.
In the third period of the periodic table, sodium (Na) has the largest atomic radius. As you move from left to right across a period, the atomic radius decreases due to increasing nuclear charge, which pulls electrons closer to the nucleus. Sodium, being the first element in the period, has the least effective nuclear charge acting on its outer electrons, resulting in a larger atomic radius compared to the other elements in the third period.
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.
Potassium has the largest atomic radius.
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.
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.
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.
Sodium (Na) has a larger atomic radius than aluminum (Al).
In the third period of the periodic table, sodium (Na) has the largest atomic radius. As you move from left to right across a period, the atomic radius decreases due to increasing nuclear charge, which pulls electrons closer to the nucleus. Sodium, being the first element in the period, has the least effective nuclear charge acting on its outer electrons, resulting in a larger atomic radius compared to the other elements in the third period.
a) Sc,Ti,V,Crb) Na,K,Rb,Csc) B,Si,As,Ted) F,Cl,Br,Ie) Na,Mg,Al,SiThe correct answer of these options is a) Sc,Ti,V,Cr because they are the closest elements to each other in the periodic table.
