What is the best method to classify a chemical substance?
What is a Chemical Substance: A chemical substance is any material with a known chemical composition
Types
Mixture: a substance made by mixing other substances together
Element:
An element is a substance whose atoms all have the same number of protons
Compound: A compound is a substance made up of two or more different chemical elements combined in a fixed ratio
Bonds
Metallic Bond: A metallic bond is a type of chemical bond that occurs between atoms of metallic elements, such as copper, iron, or gold.
Covalent Bond: A covalent bond is a type of chemical bond that occurs when two atoms share electrons. In a covalent bond, atoms come together to achieve a more stable electron configuration by sharing one or more pairs of electrons between them.
Ionic bond: An ionic bond is a type of chemical bond that occurs between atoms when one atom transfers one or more electrons to another atom.

Ways to classify a chemical substance
Conductivity tester
Covalent bonds cannot conduct electricity
Ionic and metallic bonds can conduct electricty
pH tester
pH<7= Covalent
pH>7=Ionic
Observing its physical properties
Texture
Colour
Shape
Method: The process of objectively establishing facts through testing and experimentation
