Interpretation : The atomic properties of the group 13 and group 14 elements are to be compared and contrasted.
Concept Introduction : The electron configuration, atomic size, ionization energy, electronegativity, and
The group 13 and group 14 elements have similar sizes and similar trends in atomic radii and ionic radii they differ in valence electrons, oxidation number, property of allotropes, and ionization energy.
The electronic configuration of group 13 and group 14 elements are compared.
There are 3 valence electrons in group 13 while there are 4 valence electrons in group 14.
The oxidation number of group 13 is +3 while the oxidation number of group 14 is +2 and +4.
Group 14 elements form different allotropes while group 13 does not form allotropes.
The size of the elements in group 13 and group 14 are mostly similar.
In both group 13 and group 14 elements, the ionic and atomic radii down the group decrease.
The group 14 elements have higher ionization energy than the group 13 elements.
