is that proton is (particle) positively charged subatomic particle forming part of the nucleus of an atom and determining the atomic number of an element; the nucleus of the most common isotope of hydrogen; composed of two up quarks and a down quark while protium is (isotope) the lightest andRead More →
Hydrogen is found almost everywhere in the universe. It occurs between and within stars, and in the enormous gas and dust clouds that exist throughout interstellar space. Scientists have known since the 1970s that bonds between hydrogen atoms form on the very cold surface of interstellar dust grains. How isRead More →
Once a star has begun nuclear fusion, it is known as a main sequence star. When a main sequence star begins to run out of hydrogen fuel, the star becomes a red giant or a red supergiant. Is the universe running out of hydrogen? Of course, no matter what happens,Read More →
Use a 3 percent concentration of hydrogen peroxide. Anything stronger is likely to cause irritation. Mix two parts water with one part hydrogen peroxide. Gargle, swishing the solution all around the mouth. What percent peroxide do dentists use? At-home trays use about 22 percent. Professional dental whitening solutions, on theRead More →
Warm tap water is recommended for cleaning most wounds. Warm saline (salt solution) may also be used. This may be made by adding approximately one level teaspoonful (5 mL) of salt (or Epsom salts) to two cups (500 mL) of water. Will peroxide hurt a dog if they drink it?Read More →
The electron in the hydrogen h y d r o g e n atom undergoes transition from higher orbitals to orbital of radius 211.6 pm. This transition is associated with Balmer series. Hence, the transition is from higher orbit to second orbit. This corresponds to Balmer series. When an electronRead More →
The reason why the hydrogen can be placed in both group 1 and group 17 is that it resembles Alkali metals in some of its properties like it can easily form cations so, it can be placed in Group 1 of periodic table but it also resembles Halogens in itsRead More →
Although concentrations of 10% carbamide peroxide (equivalent to approximately 3% hydrogen peroxide) are most commonly used, bleaching systems containing up to 22% carbamide peroxide are available for home use. What’s the difference between carbamide and hydrogen? The main difference between hydrogen peroxide and carbamide peroxide is that hydrogen peroxide isRead More →
Underpotential deposition (UPD), in electrochemistry, is a phenomenon of electrodeposition of a species (typically reduction of a metal cation to a solid metal) at a potential less negative than the equilibrium (Nernst) potential for the reduction of this metal. What is electrolytic deposition? The production of a metal from aRead More →
You can use hydrogen peroxide to fade your denim items. It just may take a little longer than if you used chlorine bleach. One thing hydrogen peroxide does is help remove that yellow tint from your jeans if the bleach left that tint behind. Does hydrogen peroxide have a bleachingRead More →
