Single Idea 17476

[filed under theme 27. Natural Reality / F. Chemistry / 2. Modern Elements ]

Full Idea

Elements survive chemical change, and chemical explanations track them from one composite substance to another, thereby explaining both the direction of the chemical change, and the properties of the substances they compose.

The 11 ideas from Robin F. Hendry

Elements survive chemical change, and are tracked to explain direction and properties [Hendry]
Defining elements by atomic number allowed atoms of an element to have different masses [Hendry]
Generally it is nuclear charge (not nuclear mass) which determines behaviour [Hendry]
Nuclear charge (plus laws) explains electron structure and spectrum, but not vice versa [Hendry]
Maybe two kinds are the same if there is no change of entropy on isothermal mixing [Hendry]
Maybe the nature of water is macroscopic, and not in the microstructure [Hendry]
The nature of an element must survive chemical change, so it is the nucleus, not the electrons [Hendry]
Maybe water is the smallest part of it that still counts as water (which is H2O molecules) [Hendry]
Compounds can differ with the same collection of atoms, so structure matters too [Hendry]
Water continuously changes, with new groupings of molecules [Hendry]
Supervenience is simply modally robust property co-variance [Hendry]
