they have thriving electronegativities.
the thermal conductors isn't very good
the Brittle solids are not malleable and you cant do anything
and there are Poor electrical conductors.
That is all i know hope this helps
some things i know that may helpp are these High ionization energies.
High electronegativities.
Poor thermal conductors.
Poor electrical conductors.
Brittle solids—not malleable or ductile
