200

Arrange the following in order of increasing atomic radius (smallest first): Na, Si, Cl. Explain your reasoning.

Cl < Si <Na

Na, Si and Cl are all period 3 elements and atomic radius decreases from left

to right across a period because of increasing nuclear charge and the electron

shielding remains constant.
