They tend to be lustrous, ductile, malleable, and good conductors of electricity, while nonmetals are generally brittle (for solid nonmetals), lack lustre, and are insulators. If the fractured pieces of a brittle fracture are fitted together, the … brittle, crisp, and fragile mean easily broken. 3. Since in ionic bonding every other atom is of opposite charge when a row of atoms attempts to slide past another row, positive atoms encounter positive atoms and negative atoms encounter negative atoms. We will talk more about ductile materials in the next section. This was about 46% of all the recorded Brittle's in the USA.
