They are flexible, brittle

Three characteristics of nonmetals are:

1. Poor conductors: Nonmetals generally have low conductivity for heat and electricity. This is because they have fewer free electrons available for conducting electricity or transferring heat.
2. Brittleness: Nonmetals are typically brittle, meaning they break or shatter easily when subjected to force or pressure. Their lack of metallic bonding makes them prone to fracture.
3. Dull appearance: Unlike metals, which have a shiny or metallic luster, nonmetals usually have a dull or non-reflective surface. They do not reflect light as effectively due to their atomic structure.
