What I've never understood is how the atomic nuclei has such influence on macroscopic chemical properties. The only useful property of the nuclei is its charge - an integer number, so all macroscopic effects should be completely defined by that integer alone, and all properties of water are sufficiently described by just three numbers - 1, 8, 1 (in any order).

Thus the atoms on the same columns having comparable properties by having the same layers occupied by electrons. and that's the "I flunked the exam" version, I'm sure this level of explanation is ridiculously simplified compared to the real deal ;)
- tcpekin 5y agoThe number of available valence shell electrons, not the atomic nuclei is typically the controlling factor for macroscale chemical properties of elements. This typically is in balance with the nucleus' positive charge, but does not have to be. Water molecules are molecules, and therefore have a more complex electronic structure than atoms, and therefore is harder to describe, especially at the extremes.
