Which statements correctly compare metals and nonmetals

1. Metals are generally solid at room temperature, while nonmetals can exist as gases, liquids, or solids.

2. Metals tend to have high melting and boiling points, while nonmetals have lower melting and boiling points.
3. Metals are good conductors of heat and electricity, while nonmetals are poor conductors.
4. Metals are malleable and ductile, meaning they can be easily shaped into different forms, while nonmetals are generally brittle and cannot be easily stretched or shaped.
5. Metals tend to have a shiny appearance, while nonmetals are usually dull in appearance.
6. Metals tend to react with acids to produce hydrogen gas, while nonmetals do not typically react with acids in this way.
