Describe the Periodic Trends for Atomic Radius.
The atomic radius of an element tends to increase the further down you go in an element group. The atomic radius of atoms generally decreases from left to right across a period. Periodic Trends Made Easy Chemtalk Describe the trends in atomic radii by checking the correct box. . The chemistry and atomic structure of the elements is a contest between i nuclear charge conveniently represented by Zthe atomic number and ii shielding by other electrons. B Covalent radii of the elements are shown to scale. Identify which of the following atoms would have the largest radius. There are some small exceptions such as the oxygen radius being slightly greater than the nitrogen radius. However this does not happen. The reason is that the probability for finding the electron never becomes zero. An atom gets larger as the number of electronic shells increases. B Atomic radius decreases from left to right across the perio...
