Comments

Elements 113, 114 and 115 are believed to be poor metals too. Element 116 could be either a poor metal or a metalloid. So I'm not putting the keyword full at this time. The poor metals are between the metalloids and the transition metals on the periodic table.

Examples

			The atomic number of aluminium is 13.
