Final answer:
Nonmetals have poor conductivity and low melting/boiling points.
Step-by-step explanation:
Two properties of nonmetals are:
- Nonmetals are poor conductors of heat and electricity. For example, elements like carbon, nitrogen, and oxygen do not conduct electricity well.
- Nonmetals have low melting and boiling points. They tend to be gases or brittle solids at room temperature. For instance, sulfur is a yellow solid with a low melting point.
