What are some properties of metals?
Metals are typically shiny, malleable, and good conductors of heat and electricity. They can also be ductile, meaning they can be drawn into wires.
Can you provide examples of non-metals?
Examples of non-metals include carbon, oxygen, sulfur, and nitrogen. These elements are generally dull, brittle, and poor conductors of heat and electricity.
How do metals and non-metals differ in their behavior during chemical reactions?
Metals tend to lose electrons and form positive ions during chemical reactions, while non-metals usually gain electrons and form negative ions. This fundamental difference in electron behavior contributes to their distinct properties and reactivity.
