I believe the scientific property referes to the composition, on an atomic level, of an element or compound. It's property(ies) are what constitutes the element in an isolated state, but also how it reacts to changes in environment: (temperature, humidity, etc..); but also how it reacts to other elements. What changes occur and if it has the potential to change it's molecular "structure".
The levels, from smallest to largest, are: molecule, cell, tissue, organ, organ system, organism, population, community, ecosystem, biosphere.
