In contact with air, calcium develops an oxide and nitride coating, which protects it from further corrosion.
gold is an element
This chemical property is called reactivity.
An element's ability to react with oxygen is an example of a chemical property. This property describes how elements interact with other substances to form new compounds. In this case, the element's reactivity with oxygen shows its tendency to form oxides.
Zinc is neither. Zinc is an element it HAS physical and chemical properties. For example Zinc is soft this is a physical property
Zinc is not a property; it is a substance. Like all substances it has its own set of physical and chemical properties.
Physical properties of an element are those in which there is no change in its state. For example, the color and density of an element are physical properties. If an element is flammable, it goes through a reaction and burns, and there is a change in state. When there is a reaction that results in a change of state, Flammability is a chemical property.
Reactivity is an example of a chemical property.
Chemical Property
Burning is an example of a chemical property because it can only be observed during a chemical reaction called combustion.
It's not a property but it is a change , a chemical change.
Flammability is a chemical property.Density is a physical property.
Flammability is an example of the chemical property.
