Examples: valence (II or IV), soluble in acids and alkalis.
Sharpness is a physical property. Sharpening is not a property, it is an action designed to produce a property.
Luster is a physical property of crystals.
Density is a physical property; physical properties are measurable.
I believe that you are referring to physical properties. They are observed without changing composition of the substance. Physical properties are more obvious things like colour, shape, etc.
Shape, size, and color. :)
Examples of physical properties of pencils: color, hardness, density.
This type of property is a physical property.
A physical property of a material is an intrinsic characteristic of this material; examples: density, hardness, refractive index, boiling point etc. This not depends on the material mass. The physical quantity is a measure of the property; examples: g/cm3, volt, pascal, coulomb etc.
Examples: mass, volume, density, color.
the amount of lemon juice in a bottle of lemonade
Examples: flammability, corrosivity, chemical reactivity.

Physical properties can be observed without chemically changing the substance. Examples include mass, volume, and density.
Physical Property are those that can be observed or measured without affecting the composition of the sample. Density, hardness, viscosity, malleability, solubility, melting temperature, and boiling temperature are some examples of physical property.
The International System of Units (SI) is used to express physical properties. The SI unit for a physical property depends on the specific property being measured. Examples include meters for length, kilograms for mass, seconds for time, and Kelvin for temperature.
Physical properties can be observed without altering the chemical composition of the substance. Examples include color, shape, size, density, and melting point.
