An atom has same number of protons and electrons so the atom is electrically neutral. A proton has same mass as a neutron.Table 1 shows charges and masses of sub-atomic particles. Particle Relative mass Relative charge Proton 1.0 1+ Neutron 1.0 0 Electron 1/2000 1-...

Since the charge of the proton is a positive one, the number of protons vs. electrons in an atom is important in determining the charge of the atom. There is one atom that has only a single proton and no neutrons: hydrogen. As a neutron has no actual electrical charge, the only charge...
Driven by carbon neutral targets, proton exchange membrane water electrolysis is becoming a hot technology due to its capability to convert fluctuating power into green hydrogen. Unfortunately, despite tremendous resources invested in fundamental research, only very few research outcomes have successfully tr...
protons combine with other protons by means of nuclear fusion. This fusion requires a temperature of approximately 1 million degrees Celsius. This high temperature causes two lighter particles to fuse into a third particle. The mass of the created particle is less than that of the two initial pa...
the most up-to-date combination of results on the properties of the Higgs boson, including the most stringent limit on the cross-section for the production of a pair of Higgs bosons, on the basis of data from proton–proton collisions at a centre-of-mass energy of 13 teraelectronvolts....
In summary, the strong force is one of the four fundamental forces of nature responsible for binding the nuclei of atoms together. It is carried by gluons and only affects particles that are very close together. Its strength can be calculated using a complex formula and is approximately 100 ...
There are groups or multiplets with almost the same mass, within one or two percent. Each particle in a multiplet has the same strangeness. The first multiplet is the proton-neutron doublet, and then there is a singlet (the lambda) then the sigma triplet, and finally the xi doublet. ...
The coumarin-derived racemic mixture, warfarin, at peak usage was estimated to be taken by at least 1% of the whole UK population, and by 8% of those aged over 80 years [11]. However, warfarin usage has decreased in many European countries and in the US, with a concomitant increase in...
5, 6) showed the presence of two methyl groups (δH 4.27, 4.44; δC 43.3, 57.7) and one aromatic proton (δH 9.14). Because there are too many quaternary carbon and nitrogen atoms in the molecule, it was difficult to further determine the planar structure of PM-3. Fortunately, a ...
