Here are the essential concepts you must grasp in order to answer the question correctly.
Physical Property
A physical property is a characteristic of a substance that can be observed or measured without changing its chemical identity. Examples include color, odor, boiling point, and state of matter. In the case of neon being a colorless gas at room temperature, this observation does not alter the chemical structure of neon.

Chemical Property
A chemical property describes a substance's ability to undergo a specific chemical change or reaction. This includes reactivity with other chemicals, flammability, and acidity. Unlike physical properties, chemical properties can only be observed during a chemical reaction, which is not applicable to the description of neon as a gas.

State of Matter
The state of matter refers to the distinct forms that different phases of matter take on, primarily solid, liquid, gas, and plasma. Neon, being a gas at room temperature, indicates its state of matter, which is crucial for understanding its behavior and properties in various conditions.
