Does Sodium have a larger atomic radius than Aluminum?
No, aluminum has a larger atomic radius than sodium. Aluminum has a greater number of protons in its nucleus compared to sodium, leading to a larger effective nuclear charge that pulls its electrons closer, resulting in a smaller atomic radius.
Why are size of cations always smaller and size of anions always bigger than the corresponding atom?
anions always gain extra electrons casing the ionic radius to increase but cations remove electrons causing the ionic radius to decrease .therefore anionic radius is greater than cationic radius
Is barium larger than aluminum yes or no?
a general answer is that if it is a cation the ion is smaller than the atom due to loosing one or more electrons which would decrease the size of the radius anions are larger because they are gaining more electrons and electron electron repulsion is greater which spreads the anion apart
Which has the smallest radius K Rb K Rb?
Potassium's atomic radius is smaller than rubidium's because potassium has fewer energy levels of electrons.
Which has lower ionization energy an atom with a small radius or an atom with a large radius?
An atom with a larger radius typically has lower ionization energy. This is because in larger atoms, the outermost electrons are farther from the nucleus and experience weaker attraction, making it easier to remove them compared to smaller atoms where the electrons are closer to the nucleus and held more tightly.
Does Sodium have a larger atomic radius than Aluminum?
No, aluminum has a larger atomic radius than sodium. Aluminum has a greater number of protons in its nucleus compared to sodium, leading to a larger effective nuclear charge that pulls its electrons closer, resulting in a smaller atomic radius.
Is boron atomicly bigger or smaller than Oxygen?
Boron has a larger atomic radius but a smaller atomic mass.
Is a proton larger or smaller than an electron?
Protons have a larger mass, but it is unclear which (if either) have a larger radius. The electron does not seem to have ANY measurable radius.
Does an atom of fluorine have larger or smaller radius than an atom of iodine?
Smaller
What happens to an atomic radius when an electrons is lost?
The positive ionic radius is smaller than the neutral atomic radius
Why are size of cations always smaller and size of anions always bigger than the corresponding atom?
anions always gain extra electrons casing the ionic radius to increase but cations remove electrons causing the ionic radius to decrease .therefore anionic radius is greater than cationic radius
Does fluorine or bromine have a larger value in ionic radius?
Bromine has a larger value in ionic radius compared to fluorine. Fluorine is a smaller atom due to more effective nuclear charge and stronger attraction to its electrons. Bromine, on the other hand, is a larger atom with more electron shells, resulting in a larger ionic radius.
What occurs to the radius when an atom loses an electron?
The negative ionic radius is larger than the neutral atomic radius

When an atom becomes an an ion what happens to it's radius?
The atomic radius of a cation is smaller than that of its original atom. See the related link for an image example of what this may look like.
