what are the chemical and physical properties of radon?
11189
Radon is colorless at standard temperature and pressure and it is the most dense gas known. At temperature below it's freezing point is has a brilliant yellow phosphorescence. It is chemically unreactive, it is highly radioactive and has a short half life.

Physical Properties. A physical property is a characteristic of a substance that can be observed or measured without changing the identity of the substance. ... Physical properties of matter include color, hardness, malleability, solubility, electrical conductivity, density, melting points, and boiling points.

Physical characteristics Because most gases are difficult to observe directly, they are described through the use of four physical properties or macroscopic characteristics: pressure, volume, number of particles (chemists group them by moles) and temperature.

Radon is a radioactive gas with no taste, smell or color. This means the human senses alone cannot detect it. That is why, although radon was discovered in 1899 and even back in 1530 Paracelsus noticed some health effects in miners, regulation and radon's connection to lung cancer are fairly new.

Physical properties include color, density, hardness, and melting and boiling points. A chemical property describes the ability of a substance to undergo a specific chemical change. To identify a chemical property, we look for a chemical change.

These physical properties can be physical state, magnetic and electrical properties, specific gravity, density, melting point, boiling point and solubility. Here are some of the different methods of separating mixtures. Different compounds have different amounts of solubility at a specific temperature.

Physical properties can be observed or measured without changing the composition of matter. Physical properties are used to observe and describe matter. Physical properties include: appearance, texture, color, odor, melting point, boiling point, density, solubility, polarity, and many others.

Radium is silvery, lustrous, soft, intensely radioactive. It readily oxidizes on exposure to air, turning from almost pure white to black. Radium is luminescent, corrodes in water to form radium hydroxide. Although is the heaviest member of the alkaline-earth group it is the most volatile.

Some properties of an element can be observed only in a collection of atoms or molecules of the element. These properties include color, density, melting point, boiling point, and thermal and electrical conductivity.

Nitrogen family elements display a wide range of physical and chemical properties. Their compounds may be transparent, either diamagnetic or paramagnetic at room temperature, and may conduct electricity when heated. Because the atoms form double or triple bonds, the compounds tend to be stable and potentially toxic.

The Properties. Each material has physical, mechanical and chemical properties. These include density, yield strength, elasticity, Ductility, toughness, fatigue limit and corrosion resistance. Density is an obvious property.

physical and chemical properties. Examples of physical properties are: color, smell, freezing point, boiling point, melting point, infra-red spectrum, attraction (paramagnetic) or repulsion (diamagnetic) to magnets, opacity, viscosity and density. There are many more examples.

Chemical properties are characteristic properties of elements shown during chemical change. Chemical properties are properties of an element or compound that are seen during any chemical reactions.
