A pure substance is a sample of matter that has definite physical as well as chemical properties. A pure substance can be either a single compound, or a single element.
A Substance.
You think probable to an atom.

A uniform mixture is : A sample of matter that has the same composition and properties throughout.
The smallest particle of matter that retains the properties of the element of which it is a sample.
multiple property of matter i think
In chemistry, an intensive property is a property that depends on the type of matter in a sample.
The reactants are transformed in products, substances with another type of molecules and properties.
A uniform mixture is : A sample of matter that has the same composition and properties throughout.
term for that is pure substance
Pure substance: matter w/properties/composition that don't vary from sample to sample. (salt, water,etc). Homogeneous mixture: composition can vary; an example is a solution (coffee w/sugar) and is uniform throughout.
composition
Yes they wouldn't have the same composition but not properties!
Wood is Heterogeneous Mixture because, the properties and composition are not uniform throughout the sample. Note : Wood is an organic composite of consisting of cellulose and lignin. Vineet Aggarwal
Mass is an extensive property, which depends only on the amount of matter in the sample, not on the composition of the sample.

Chemical properties
The smallest particle of matter that retains the properties of the element of which it is a sample.
