Metals are lustrous, malleable, ductile, good conductors of heat and electricity.
What are the 8 chemical properties of minerals?
Properties that help geologists identify a mineral in a rock are: color, hardness, luster, crystal forms, density, and cleavage. Crystal form, cleavage, and hardness are determined primarily by the crystal structure at the atomic level. Color and density are determined primarily by the chemical composition.
Is odor a chemical property?
Characteristics such as melting point, boiling point, density, solubility, color, odor, etc. are physical properties. Properties that describe how a substance changes identity to produce a new substance are chemical properties.
What are the chemical properties of bleach?
Bleaching. Household bleach is, in general, a solution containing 3–8% sodium hypochlorite, by weight, and 0.01–0.05% sodium hydroxide; the sodium hydroxide is used to slow the decomposition of sodium hypochlorite into sodium chloride and sodium chlorate.
What are the chemical properties of fluorine?
Fluorine is the most reactive and the most electronegative of all the elements. Fluorine is a pale yellow, diatomic, highly corrosive, flammable gas, with a pungent odor. It is the lightest halogen. It reacts violently with water to produce oxygen and the extremely corrosive hydrofluoric acid.

What are physical and chemical properties?
Physical properties are those that can be observed without changing the identity of the substance. … Properties that describe how a substance changes into a completely different substance are called chemical properties. Flammability and corrosion/oxidation resistance are examples of chemical properties.
What is chemical change explain with example Class 6?
Chemcial Change When a new substance is formed after the change, it is called chemical change. Chemical changes cannot be reversed by simple physical means. Many chemical changes are irreversible. Examples: Burning of candle, rusting of iron, etc.
