| 17486 | Supervenience is simply modally robust property co-variance |
| 17481 | Nuclear charge (plus laws) explains electron structure and spectrum, but not vice versa |
| 17478 | Maybe two kinds are the same if there is no change of entropy on isothermal mixing |
| 17479 | The nature of an element must survive chemical change, so it is the nucleus, not the electrons |
| 17484 | Maybe the nature of water is macroscopic, and not in the microstructure |
| 17485 | Maybe water is the smallest part of it that still counts as water (which is H2O molecules) |
| 17476 | Elements survive chemical change, and are tracked to explain direction and properties |
| 17483 | Water continuously changes, with new groupings of molecules |
| 17482 | Compounds can differ with the same collection of atoms, so structure matters too |
| 17477 | Defining elements by atomic number allowed atoms of an element to have different masses |
| 17480 | Generally it is nuclear charge (not nuclear mass) which determines behaviour |
