Because protons are positively charged while electrons carry a negative charge equal in magnitude to the proton's charge, the atom itself is neutral, as neutrons, befitting their name, have no charge. On the other hand, protons and neutrons are very similar in mass and occupy the center of ...
aThis generates different kinds of holes of negative charge density due to the presence of Al3+, and the net negative charge can be balanced by metallic cations, protons or cationic complex. 这引起不同的种类负电荷密度孔由于Al3+出现,并且净负电荷可以由金属正离子、氢核或者负离子复合体平衡。[tr...
The negative terminal (red) is made of platinum, a precious metal catalyst designed to speed up the chemistry that happens in the fuel cell. When atoms of hydrogen gas reach the catalyst, they split up into hydrogen ions (protons) and electrons (small black blobs). In case you're confused...

As was written, a particle and its antiparticle have the same mass as one another, but opposite electric charge, and other differences in quantum numbers. That means a proton has positive charge while an antiproton has negative charge and therefore they attract each other. How much antimatter ...
While the Weak force can mediate interactions between particles without changing them (this is a result that helped point the way to the discovery of the “electroweak force”), it can also carry stuff with it, like charge. By taking charge from one thing, and giving it to another...
Why do alpha particles swerve in a cathode ray tube? How can objects become electrically charged? How do charges move through a circuit? How does electricity travel through wires? What is the effect of the magnetic field on protons? Why is there a grid in a cathode ray tube? How is a...
negative charge (protons and electrons, respectively). Some materials (like metals) that are very electrically conductive have loosely bound electrons. Hence, when a voltage is applied across a metal, the electrons travel around a circuit - this flow of electrons is electric current (measured in ...
10.1038/nrm1647 Catalytic RNAs — or RIBOZYMES — provide a window into a primordial ‘RNA world’ from which ‘modern’ biology might have evolved 1 . Contemporary roles for RNA catalysis in the modern protein world can still be found in the regulation of gene expression and in protein ...
