An Introduction to Krypton
Krypton is a chemical element represented by the symbol Kr and has an atomic number of 36. It belongs to Group 18 of the periodic table, known as the noble gases. These elements are characterized by their full outer electron shells, which make them highly unreactive. Krypton is a rare gas found in trace amounts in Earth’s atmosphere.
Classification
Krypton is classified as a non-metal. It exhibits no metallic properties such as conductivity, malleability, or ductility. Its position in the periodic table, along with other noble gases, confirms its non-metallic nature.
Visual and Tactile Characteristics
At standard temperature and pressure, Krypton is a colorless and odorless gas. Due to its gaseous state, it possesses no discernible texture in the way solids do. It is invisible to the naked eye under normal atmospheric conditions.
State of Matter and Phase Transitions
Krypton exists as a gas at room temperature (approximately 20-25 °C). Its phase transition points are significantly low.
- The melting point of Krypton is approximately -157.36 °C.
- The boiling point of Krypton is approximately -153.22 °C.
These low temperatures indicate that Krypton requires extreme cooling to transition into its liquid or solid states.
