Boiling Point, Density, Color, Conductivity, Reactivy
The five properties Mendeleev used in his table were atomic mass, chemical properties, valency (oxidation state), color, and density.

Chemical properties are determined by experiments.
If it's a chemical, it has chemical properties. An oreo churro (whatever unholy abomination that might be) is a mixture of chemicals, each of which will have their own chemical properties.
helium is chemically inert and has no chemical properties

Is reacts with water not a chemical properties
Physical and chemical properties change as the result of a chemical change, which produces new products with different physical and chemical properties than the reactants.
A chemical reaction (change) results in a change in chemical properties.
A chemical reaction changes the chemical properties of substances involved by forming new substances with different chemical compositions. This can result in changes in physical properties such as color, temperature, odor, and state of matter.
Helium is inert. There are no known compounds. It has no chemical properties.
Each chemical compound has specific chemical and physical properties.
