Abstract
The usefulness of isoelectronic series (same number of total electrons and atoms and of valence electrons) across Periods is often overlooked. Here we show the ubiquitousness of isoelectronic sets by means of matrices, arrays, and sequential series. Some of these series have not previously been identified. In addition, we recommend the use of the term valence-isoelectronic for species which differ in the number of core electrons and pseudo-isoelectronic for matching (n) and (n + 10) species.

The metals next to the semi-metals show differences in behaviour from ‘typical’ metals. In particular, they are amphoteric, readily forming oxyanions in basic solution, such as stannates. For this reason, one can use the term weak metals in contrast to the supermetals, a designation sometimes used for the low-density, highly reactive, alkali metals
