Are neutrinos faster than the speed of light? Neutrinos are tiny, electrically neutral particles produced in nuclear reactions. Last September, an experiment called OPERA turned up evidence that neutrinostravel faster than the speed of light(see 'Particles break light speed limit'). Are neutrinos fa...
According to the Standard Model, the most successful description of particle physics to date, neutrinos come in three varieties, called "flavors". Again, according to the Standard Model, they are point-like, electrically neutral and massless. But in recent years, this view has been challenged, ...
Again, according to the Standard Model, they are point-like, electrically neutral and massless. But in recent years, this view has been challenged, as physicists realized that neutrinos might have mass. C. The first strong evidence came in 1998, when researchers at an experiment, based in ...
The discovery was profound. The electron was more fundamental than anything yet discovered. It was the first of the several minuscule objects now calledsub-atomicparticles to be discovered. However, atoms can’t simply confine a negative charge, because they are, of course, electrically neutral. ...

A chlorine atom, found in the periodic table's halogen group, has 17 protons and 17 electrons, making it electrically neutral. It often participates in reactions by gaining an electron to achieve a stable electronic arrangement. The chloride ion, on the other hand, results from this gain of ...
The car industry faces some extreme challenges. Alongside the key task that we face of making individual transport climate-neutral, and alongside the new technological opportunities for communication and networking across our whole environment, it is cle
This research doesn't just challenge our understanding of memory, it opens up new frontiers of scientific exploration. If cells throughout the body can "remember" and "learn," what does that mean for our health and understanding of the biological processes that make up an individual? Lead rese...
Why are objects with vast number of electrons normally not electrically charged? Why do we have free electrons in metal and not in insulators? What makes them be an insulator/semiconductor/metal? Why do electrons just drift, and how do we know that if we can'tsee them? Why does their sp...
Answer and Explanation:1 A negatively charged atom is called an anion.Anions are usually formed when non metals accept additional electrons from metallic elements. These... Learn more about this topic: Anion | Definition, Properties & Examples ...
