Atomic Radius

1) Using only the periodic table, arrange each set of atoms in order of increasing radius. Rank from smallest to largest. To rank items as equivalent, overlap them.

a) Be, Mg, Ca

b) Ge, Br, Ga

c) Si, TI, Al

2) Rank the following elements in order of decreasing atomic radius.Rank from largest to smallest radius. To rank items as equivalent, overlap them.

a) Cl, I, F, Br
b) C, B, O, F

Solution Summary

This solution explains how to rank atoms in terms of increasing and decreasing atomic radius.
