Physical vs. Chemical Properties
Physical Properties - can be observed without changing the identity of the substance.
- melting point
- electrical
- conductivity
- color density
- boiling point
- thermal conductivity
- odor
- hardness
- refractive index
- atomic radius
- ductility
- ionization energy
- allotropes
- malleability
Chemical Properties - can not be observed without changing the identity of the substance.
- electronegativity
- ionization potential
- flammability
- oxidation state(s)
- coordination number
- types of bonds to form e.g., metallic, ionic, covalent
