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
