To a first approximation, atoms generally behave like minute spherical objects. The atomic radius of a chemical element is a measure of the size of its atoms, usually the distance from the nucleus t...

Along a period (left to right) the the atomic number increases while the valence electrons remain in the same shell. Thus due to the increasing nuclear charge (pulling electrons closer to the nucleus) the radii of the atoms decrease left to right. ... The result is atomic radii increase top to bottom along a group.

Click on elements in colored boxes to see the sizes of their atomic radii. ... Atomic radii vary according to the position of the element on the periodic table. The arrows you just drew show that higher period elements have larger atomic radii; elements with fewer valence shell electrons also have larger atomic radii...

The illustration above is a plot of "covalent radii" (from Ebbing) which are determined by measuring the bond lengths in the molecules of chemical compounds. Another way to determine characteristic radii is to measure ionic radii in crystals ... The atomic radius is one of the parameters used in quantifying chemical bonds...
