Answer 2

Answer:

Chemical Properties of Nonmetals

• Nonmetals are poor conductors of heat and electricity. ...
• Unlike metals, nonmetals aren't malleable and ductile.
• Nonmetals react more with metals than with nonmetals.
• Usually, nonmetals react with other nonmetals in high temperature.
• Most nonmetals do not react with air in room temperature.
