This is a consequence of two factors: (i) nuclear charge; and (ii) shielding by other electrons. Incomplete electronic shells shield nuclear charge very ineffectively, and thus atomic radii decrease markedly across the Period to give the Noble Gases as the smallest atoms of their Period.

It is arranged in order of atomic size (Hydrogen, then Helium, then Lithium, etc.) which is determined by the number of protons in the element. The table is subdivided into periods (rows) and groups (columns) of elements that share common characteristics, hence the name "periodic". popular james patterson books
