chemical property
"Very reactive" is a chemical property because it describes how likely a substance is to undergo a chemical reaction with other substances. It does not pertain to any physical characteristic of the substance.
Chemical
By the very fact that your have written 'reaction' , it is a chemical property.
Yes, reactivity to water is a chemical property of copper, not a physical property. Copper does not react with water at room temperature, but it can slowly react with water when exposed to high temperatures or steam to form copper oxide.
They are very reactive.
Yes, chlorine is a very reactive chemical element.
No, lithium (Li) and fluorine (F) have different chemical properties. Lithium is a metal and is highly reactive, while fluorine is a nonmetal and is a very reactive halogen. They belong to different groups on the periodic table and have distinct physical and chemical characteristics.
Reactivity is a chemical property, not a change.

Cesium is the most chemically reactive metal.
The explosiveness of fireworks is a chemical property because it is a result of the chemical reactions that occur within the fireworks composition. The specific combination of chemicals and their reactions determine the colors, sounds, and overall explosiveness of the fireworks.
