proton affinityhydrogen atom affinityionisation energygas-phase ion chemistryFrom the NIST website and the literature, we have collected the Ionisation Energies (IE) of 3,052 and the Proton Affinities (PA) of 1,670 compounds. For 614 of these, both the IE and PA are known; this enables a...
Proton.A proton and an electron have same kinetic energy. Which one has smaller de-Broglie wavelength ?
The total relativistic energy of a particle of rest mass m0, momentum p is E=sqrt(p^2c^2+m0^2c^4) As de-broglie wavelength is same for electron and proton, i.e., lambdae=lambdap or h/(pe)=h/(pp) so pe=pp. So minimum is same for them. so p^2c^2 is
The matter is constituted of positively charged protons and negatively charged electrons. For a neutral matter, the number of protons equals the number of electrons. The charge of each electron and each proton are equal and opposite of each other....

Different from the traditional two-electron oxidative addition-transmetalation-reductive elimination coupling strategy, visible light has been successfully integrated into transition metal-catalyzed coupling reaction of propargylic alcohol derivatives highly selectively forming allenenitriles: specifically speaking, ...

Therefore, CuBr2 plays two roles in this one-step oxidation reaction: (a) oxidation of fullerene via electron transfer with assistance of bromide anion, (b) proton transfer for formation of the hemiketal through the formation of Br–. Fig. 6: DFT calculations. DFT calculation for the key ...
Precision conversion-electron and γ-ray measurements have revealed a strong M1 transition of 10.84 keV between the first and the second excited states of 206Bi, resulting in a substantial revision of the previous decay scheme of 206Po. Thus it has become possible to interpret some of the low...
