Do we understand chemistry from particle physics?

While the discoveries of the rules of chemistry and some current practical wisdom is empirical, it is better to think of the entire nature of chemistry as dictated by the principles of quantum ...

Do we understand chemistry from particle physics?

atoms have 8 electron "slots" in their outer shell The shape of the periodic table is one of the great successes of non-relativistic quantum mechanics. If we approximate that we're ...

Why do valence electrons not push each other away?

First of all, the electrons do exert a repulsive force on one another. This is inherently accounted for in the electrostatic repulsion terms in the atomic Hamiltonian that is used to solve the ...

Do we understand chemistry from particle physics?

"Do we understand chemistry from particle physics?" I suggest that the answer is 'no', but some people believe on a theoretical basis that we should be able to understand chemistry from ...

General Doubt. My doubt about combustion

Boiling water is not hot enough to ignite the paper. If you were to pour molten metal on the paper instead then it would burn. Note that the source of oxygen is from the surrounding air - the fact ...

Why do valence electrons not push each other away?

Technically you would account for interactions between elections in multi-electron atoms, and this interaction would be repulsive, but there is no issue with there being a repulsion. This is where the ...

Do we understand chemistry from particle physics?

No. The problem with understanding chemistry from particle physics is the quantum solutions of anything more than Hâ‚‚ simply don't exist as analytic solutions. We can grind through particle physics on ...

Do we understand chemistry from particle physics?

We can build much of chemistry from non-relativistic quantum mechanics (NRQM). However, the "Standard Model" is relativistic quantum field theory (RQFT); and a direct derivation would ...

General Doubt. My doubt about combustion

Boiling water is not hot enough to start paper on fire, which happens around 450 degrees F. Now we note that water is noncombustible; the oxygen and hydrogen it contains are chemically locked up to ...

Do we understand chemistry from particle physics?

As you can see from the wide range of answers, the answer to your question is rather philosophical, so even practicing chemists and physics do not necessarily agree on it. We believe that all chemical ...

Do we understand chemistry from particle physics?

Chemistry has a theoretical basis drawn from quantum mechanics, but relies on experimentation to confirm it's findings. Chemists reason about chemical properties (e.g. reactivity, oxidation states, ...

A problem to find the the chemical potential from the free energy (Ginzburg-Landau/Cahn-Hillard)

The free energy is $F[c] = \int d^n x \frac{1}{4}{\left(c^2-1 \right)^2 + \frac{\gamma}{2} \lvert \nabla c \rvert^2}$. In the grand canonical ensemble, the chemical potential is fixed, and the density ...
