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) has a larger atomic radius than aluminum (Al).
The largest radius is Na (sodium), as it has more electron shells than Al (aluminum). Sodium has an additional electron shell compared to aluminum, leading to a larger atomic radius.
Atomic radii become larger as you go from top to bottom of the periodic chart, but they get smaller as you go from left to right. Therefore, the elements with the smallest radii are in the upper right hand corner. Of S, Al, Na, and Ba, sulfur is the closest to the upper right corner and has the smallest radius of those elements.
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.
Na+ is smaller than Na.
Al is the symbol for Aluminum, Na is the symbol for Sodium, and O is the symbol for Oxygen.
Potassium has the largest atomic radius.
There are approximately 1.20 x 10^23 atoms in 0.200 mol of sodium (Na). This is because one mole of any substance contains Avogadro's number of particles, which is 6.022 x 10^23 particles.
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.
The neutral atom of potassium has the largest radius.
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.
