Respuesta :
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
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
