There is no reason to use magnesium in light bulbs. Magnesium readily and easily catches fire and burns -- white hot.
The property that describes how easily a substance catches fire and burns is called flammability. It measures the ability of a material to ignite and sustain combustion when exposed to a heat source.
The chemical that burns in air is oxygen. Oxygen is a highly reactive gas that readily supports combustion, which is why it is essential for most combustion processes to occur.
The chemical property described is called flammability.
Sodium is a metal that burns readily underwater. When exposed to water, sodium reacts vigorously, releasing hydrogen gas and generating enough heat to ignite the hydrogen, resulting in a bright yellow flame.
"Burns easily" is a physical property of a material because it describes how the substance reacts to a specific type of external stimuli (in this case, heat or fire). It is not an inherent part of the substance's chemical composition.
Because it burns readily and with a bright flame.
it catches fire
Kindling, such as small dry twigs or paper, are materials that burn easily and are commonly used to start a fire. These materials ignite quickly and help to initially build the flame before larger fuel sources can catch fire. It's important to exercise caution when using kindling to start a fire to prevent accidents.
If you burn something it is a chemical change, however if you melt of boil it, it is a physical change.
flammability. It indicates the substance's ability to ignite and sustain combustion. Highly flammable materials ignite readily and burn rapidly.
Something that burns or is flammable would be a chemical change.
