Single Idea 17392

[filed under theme 27. Natural Reality / F. Chemistry / 1. Chemistry ]

Full Idea

A central mystery of chemistry is how the elements survive in the compounds they form. For example, how can poisonous grey metal sodium combine with green poisonous gas chlorine, to make salt, which is non-poisonous and essential for life?

Gist of Idea

How can poisonous elements survive in the nutritious compound they compose?

A Reaction

A very nice question which had never occurred to me. If our digestive system pulled the sodium apart from the chlorine, we would die.

In chemistry every substance pushes, and thus creates new substances [Nietzsche]
Chemical atoms have two powers: to enter certain combinations, and to emit a particular spectrum [Harré/Madden]
Chemistry is not purely structural; CO2 is not the same as SO2 [Harré/Madden]
An acid is just a proton donor [Rosen]
The shape of molecules is important, as well as the atoms and their bonds [Watson]
Compounds can differ with the same collection of atoms, so structure matters too [Hendry]
Water continuously changes, with new groupings of molecules [Hendry]
How can poisonous elements survive in the nutritious compound they compose? [Scerri]
Periodicity and bonding are the two big ideas in chemistry [Scerri]
Chemistry does not work from general principles, but by careful induction from large amounts of data [Scerri]
The electron is the main source of chemical properties [Scerri]
Does radioactivity show that only physics can explain chemistry? [Scerri]
A big chemistry idea is that covalent bonds are shared electrons, not transfer of electrons [Scerri]
Over 100,000,000 compounds have been discovered or synthesised [Weisberg/Needham/Hendry]
'H2O' just gives the element proportions, not the microstructure [Weisberg/Needham/Hendry]
Water molecules dissociate, and form large polymers, explaining its properties [Weisberg/Needham/Hendry]
It is unlikely that chemistry will ever be reduced to physics [Weisberg/Needham/Hendry]
Quantum theory won't tell us which structure a set of atoms will form [Weisberg/Needham/Hendry]
For temperature to be mean kinetic energy, a state of equilibrium is also required [Weisberg/Needham/Hendry]
We are halfway to synthesising any molecule we want [New Sci.]
