Nonsense! Why do you insist the only parameter is quantity? What really counts is pattern(shape, geometry), and patterns require certain minimum quantities. A molecule is not simply a number of atoms, its emergent (reducible) properties arise from its shape, which is what patterns the fundamental propertied of the parts into something new. A molecule of a particular shape may absorb photos of a particular wavelength. Another may form a hook shape that makes it very "sticky". Another may act as a catlist by moving other molecules. These properties are not simply quantitative, they are qualitative and the qualities are the properties are the "configurations" are the shapes.
Real emergence is about the appearance of collective properties as an effect of
the mutual manifestation of powers, i.e. dispositional properties, of certain numbers of certain kinds of particles which are spatially interrelated, i.e. geometrically arranged, in certain ways. What Pl0bs completely ignores is the crucial
dynamic aspect of emergence, i.e. the "power interplay" occurring among the elements of physical systems, which generates and sustains new properties had by the system as a whole but not by single elements.
