Rb is the largest, Li the smallest in the row above. Group 1 of the periodic table: Fr > Cs > Rb > K > Na > Li > H
The negative ionic radius is larger than the neutral atomic radius
Yes Atomic radius of carbon: 60 pm Atomic radius of silicon: 110 pm
Hydrogen has the smallest atomic radius - 25 pm.
Caesium atom has a larger atomic radius.
Rb
Potassium's atomic radius is smaller than rubidium's because potassium has fewer energy levels of electrons.
85.4678 is the atomic weight of Rb.
Noble gases have the smallest atomic radius.
Rb is larger with a radius of 248 pm while Xe has one of 130 pm. It follows the trend that radii decrease as you move right across the periodic table.

Rb is the largest, Li the smallest in the row above. Group 1 of the periodic table: Fr > Cs > Rb > K > Na > Li > H
Rubidium's atomic radius is greater than xenon's because the trend for atomic radius is that it decreases left to right across a period (even though atomic number increases, and generally speaking, atomic mass does as well.) This is a result of the attraction between the protons in the nucleus and the valence electrons, which are all in the same energy level for isoperiodic elements.
If the atoms are the same, it is the atomic radius.
The atoms with the largest atomic radii are found in the lower right side of the periodic table. Smallest atoms are found in the higher left part of the periodic table. He has the smallest atomic radii.
The atomic radius of caesium is practically identical to the atomic radius of francium.
