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. earl chambers coach
