what are the physical and chemical properties of elements?
234584
We learned that physical properties are things like shininess, conduction of heat or electricity, melting point, and density. Chemical properties include things like reactivity to oxygen, flammability, and ability to hold on to electrons during a chemical reaction.

Physical and Chemical Properties Iron, like other metals, conducts heat and electricity, has a luster, and forms positive ions in its chemical reactions. Pure iron is fairly soft and can easily be shaped and formed when hot. Its color is silvery white. Iron is easily magnetized.

['In physical property metals contains lustrous surface and can polished. [00:07]', 'Metals are solid and heavy, even though sodium, potassium, magnesium, aluminium etc. are comparatively lighter metals. [00:16]', 'Metals are excellent conductor of warm and electricity. [02:40]', 'Melting points and boiling points of metals are very high. [03:19]']

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. ... To identify a chemical property, we look for a chemical change.

Physical properties are those that can be observed without changing the identity of the substance. The general properties of matter such as color, density, hardness, are examples of physical properties. ... Flammability and corrosion/oxidation resistance are examples of chemical properties.

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.

Chemical properties describe the characteristic ability of a substance to react to form new substances; they include its flammability and susceptibility to corrosion. All samples of a pure substance have the same chemical and physical properties.
163437
The characteristic of a pure substance is that it only contains atoms of only one kind. It has fixed physical and chemical properties, for example, melting point, boiling point, density, solubility, etc.

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.

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.

Physical properties are things that are measureable. Those are things like density, melting point, conductivity, coefficient of expansion, etc. Mechanical properties are how the metal performs when different forces are applied to them. That includes things like strength, ductility, wear resistance, etc.

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.

Familiar examples of physical properties include density, color, hardness, melting and boiling points, and electrical conductivity. We can observe some physical properties, such as density and color, without changing the physical state of the matter observed.

Together, the chemical formula (the types and proportions of the chemical elements) and the crystal lattice (the geometry of how the atoms are arranged and bonded together) determine the physical properties of minerals. ... Some characteristics, such as a mineral's hardness, are more useful for mineral identification.
