Plzz ! why is hydrogen and oxygen not a physical property of water ?

Properties are qualities of something so a property of water would be that its a liquid and that has low high thermal conductivity.
Hydrogen and oxygen is just what makes up the water molecule but aren’t properties

Non metal is an element or substance that is not a metal metal is a solid material that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivitymetalloid is an element (e.g., germanium or silicon) whose properties are intermediate between those of metals and solid nonmetals. they are electrical semiconductors.

Is a logical series of steps
