Choose 4 chemical properties and 4 physical properties of Polonium. (Be sure to number your list)

Answer 1

Certainly! Here are four chemical properties and four physical properties of Polonium:

Chemical Properties:

1. Radioactivity: Polonium is a highly radioactive element, primarily emitting alpha particles due to its unstable isotopes.
2. Reactivity with Oxygen: It reacts with oxygen to form Polonium dioxide (PoO₂), a compound that occurs when Polonium burns in air.
3. Acidity of Polonium Compounds: Polonium forms compounds that can exhibit acidic properties, particularly when combined with halogens to form polonides.
4. Solubility in Nonpolar Solvents: Polonium may form various soluble compounds in nonpolar solvents, interacting differently depending on the chemistry of the environment.

Physical Properties:

1. Atomic Number: Polonium has the atomic number 84, placing it in the chalcogen group of the periodic table.
2. Melting Point: The melting point of Polonium is approximately 254 °C (489 °F).
3. Density: Polonium has a density of about 9.2 g/cm³, making it one of the denser elements.
4. Appearance: Polonium is a post-transition metal and appears as a silvery-gray, lustrous solid at room temperature.
