What are physical properties of an element?
A physical property is a characteristic of matter that is not associated with a change in its chemical composition. Familiar examples of physical properties include density, color, hardness, melting and boiling points, and electrical conductivity.
What is the use of phosphorus 32?
Phosphorus-32 (also known as P-32) treatment uses a radioactive form of sodium phosphate. Because P-32 is radioactive, it can be used to treat some diseases by injecting it into the body. When P-32 is injected into the bloodstream it collects in the bone marrow where it slows down the production of new blood cells.
Why is phosphorus not a metal?
Phosphorus is a non-metal. Phosphorous is a nonmetal – this is because it is a poor electrical conductor, has a relatively high electronegstivity, and a relatively high ionization energy. Nonmetallic behavior increases as you go to the right and upwards on a periodic table.
Where is phosphorus 32 found?
It is embedded in nucleic acids involved in all metabolic processes of living bodies and replaces stable phosphorus-31. As phosphorus-32 is a beta emitter, its movement within the body can be tracked using tomography. “Nucleotides including unstable phosphorus-32 are called labeled.
Where is phosphorus used?
Phosphorus is a critical plant nutrient and its key use by phosphate compounds is in the manufacture of fertilizers. Even like there are bio carbon and nitrogen cycles, there is also a phosphorus cycle. Phosphorus is used in the manufacture of safety matches (red phosphorus), pyrotechnics and inflammatory shells.
Can phosphorus kill you?
Besides, white phosphorus can cause painful diseases and even kill in a number of ways. One of the diseases eats away bones and causes them to glow.
What are properties of element?
Properties of an element are sometimes classed as either chemical or physical. 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.
What are physical and chemical properties of matter?
A physical property is a characteristic of a substance that can be observed or measured without changing the identity of the substance. 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.
What is the chemical properties of matter?
Chemical properties are properties that can be measured or observed only when matter undergoes a change to become an entirely different kind of matter. They include reactivity, flammability, and the ability to rust. Reactivity is the ability of matter to react chemically with other substances.
What are the 15 properties of matter?
The properties of matter include any traits that can be measured, such as an object’s density, color, mass, volume, length, malleability, melting point, hardness, odor, temperature, and more.
Why is phosphorus called the devil’s element?
Some texts refer to phosphorus as the “Devil’s Element” because of its eerie glow, tendency to burst into flame, and because it was the 13th known element. Like other nonmetals, pure phosphorus assumes markedly different forms. There are at least five phosphorus allotropes.
Is Phosphorus a metal or nonmetal?
Phosphorus (P, Z=15). Phosphorus is a nonmetallic element that exists in several allotropic forms (see below). It is found in the Earth’s crust at a concentration of 1000 ppm, making it the 11th most abundant element.
What is violet phosphorus used for?
Phosphorus is a common element with many industrial uses. Unfortunately, it is a key ingredient in making the street drug methamphetamine.
Why are the properties of the elements periodic?
The periodic table arranges the elements by periodic properties, which are recurring trends in physical and chemical characteristics. These trends explain the periodicity observed in the elemental properties of atomic radius, ionization energy, electron affinity, and electronegativity.
