Why weren't the electrons attracted to doubly charged Helium particles in the Rutherford experiment?
I have a chapter and in it there was a topic on the Rutherford experiment.
It is written that doubly charged helium particles or alpha particles were thrown towards a very thin gold foil and some of ...

Does H3O+ donate a H+ to Water?
Does the hydronium ion donate a proton to water? If the collision of 2 molecules of water can cause a proton to be transferred, does hydronium 'pass' a proton to water?

What is the proton NMR spectrum of p-methoxyphenol?
I think there will be two pairs of doublets, since the hydrogens adjacent to the $\ce{OCH3}$ and those adjacent to the $\ce{OH}$ group will be in different environments. The answer, however, is that ...

Quotable Literature for the Enthalpy of a Proton
A proton obviously has no electronic energy, no vibrational and no rotational degrees of freedom. Therefore I think it is fair to assume, that $$H(\ce{H+})=\frac32\cdot \mathcal{R}\cdot T$$ holds for ...

Spin spin coupling in a proton NMR of an ester?
I am learning about proton NMR and spin-spin coupling, and am confused about whether splitting occurs over an ester bond. Specifically, in the case of ethyl methanoate, HCOOCH2CH3, if I were to number ...

Will adding up protons and electrons (without neutrons) create a new element?
If protons have a positive charge and electrons have a negative charge,
can we add up several protons and electrons together to create a new element, without adding neutrons to hold the nuclei ...

Confused about strong/weak dibasic and tribasic acids
I know that sulfuric acid is considered a strong acid, and the dissociation of its first $\ce{H+}$ ion is complete and of its second $\ce{H+}$ ion is partial.
Phosphoric acid is weak and all three of ...

Hydrogen Isotopes and Bronsted Lowry Acid
a Bronsted Lowry Acid is defined as an acid that donates a proton. However it's actually a Hydrogen Ion, since hydrogen only has 1 proton and 1 electron, a positive Hydrogen Ion would have no electron ...
