Atomic radius, half the distance between the nuclei of identical neighbouring atoms in the solid form of an element. An atom has no rigid spherical boundary, but it may be thought of as a tiny, dense positive nucleus surrounded by a diffuse negative clou

The two atomic radius trends we discussed above are true for the majority of the periodic table of elements.However, there are a few exceptions to these trends. One exception is the noble gases. The six noble gases, in group 18 of the periodic table, are helium (He), neon (Ne), argon...
