Classification of Xenon
Elemental Group and Nature
Xenon is categorized as a non-metal. It belongs to Group 18 of the periodic table, known as the noble gases. These elements are characterized by a full outer electron shell, which typically results in low chemical reactivity.
Observable Physical Characteristics
Appearance and Form
Under standard temperature and pressure conditions, xenon is a colorless gas. It possesses no distinct odor. When cooled to its solid state, xenon forms a crystalline structure. As a gas, the concept of “texture” does not apply to xenon.
State at Standard Conditions
At typical room temperature (approximately 20-25 °C or 68-77 °F) and standard atmospheric pressure (1 atmosphere), xenon exists as a gas. This is a characteristic shared with other noble gases like helium and neon. Its presence in Earth’s atmosphere, though minute, demonstrates its gaseous state under ambient conditions found across various continents.
Phase Transition Temperatures
Melting and Boiling Points
Xenon transitions between its states at very low temperatures.
- Melting Point: Xenon solidifies at approximately -111.8 °C (-169.2 °F).
- Boiling Point: Xenon condenses from a gas to a liquid, or boils from a liquid to a gas, at approximately -108.1 °C (-162.6 °F).
