When hydrogen loses an electron it becomes a positively charged hydrogen ion. A hydrogen ion is therefore referred to as just a proton, as it... View Article
Free radicals are the molecules with unpaired electrons and they are unstable. Since they are unstable, they will constantly try to bind with... View Article
The pure form of nitric acid is colourless. It is very unstable when the heat is absorbed. The thermal decomposition of nitric acid produces... View Article
Sulphur as a molecule does not carry any charge. Sulphur has the electronic configuration of 2,8,6. It has to gain two more electrons to have a... View Article
Covalent hydrides are formed when hydrogen combines with one or more nonmetals to form a compound. Hydrochloric acid (HCl), in which hydrogen... View Article
When larger nuclei combine during nuclear fusion no energy will be released. Since nuclear force is a short-range force it will not act over... View Article
The average binding energy per nucleon is equal to the total binding energy divided by the total number of nucleons. Except for a few lighter... View Article
Fusion is when smaller nuclei combine to form a larger nucleus at a very high temperature and pressure. The energy released during fusion is much... View Article
An isotope of nickel, Nickel-62 with 34 neutrons and 28 protons has the highest binding energy per nucleon. The binding energy value of Nickel-62... View Article
H3O+ (Hydronium) does not have a vacant orbital in the valence shell therefore it cannot gain electrons. But it still acts as an electrophile,... View Article
The most destructive seismic wave is surface waves. The surface waves will move just under the surface of the Earth. Surface waves move the... View Article
Waves are of different types: Light waves, sound waves, ocean waves, seismic waves and many more. Light waves travel at a speed of 3 x 108 m/s in... View Article
The electromagnetic waves are the light waves. Only a small portion of the electromagnetic spectrum can be seen in the form of light. The... View Article
Waves exhibit several basic phenomena when it encounters an object. They are reflected, refracted, diffracted, polarised etc depending on the... View Article
When a material is magnetised, energy is put into it. This energy is stored in the field of the magnet. The magnetic field can be of a permanent... View Article
The kinetic energy is the result of previously stored potential energy. For example, in a battery, the chemical potential energy stored will be... View Article
The energy doesn't come from the electric field itself. The energy is due to the interaction between the charges and the electromagnetic field.... View Article
