Describe how to find the mass of an atom. Mass of the Atom: Mass of the atom is the addition of the neutron and proton that are found inside the nucleus of the atom. The SI unit of the mass of the atoms is a kilogram, but it is usually represented in a.m.u(atomic mass unit)...
The helium-4 atoms are less massive than the two hydrogen atoms that started the process, so the difference in mass is converted to energy, as described by Einstein's theory ofrelativity(E = mc²). The energy is emitted in various forms of light: ultraviolet light,X-rays, visible ...
When people refer to "amplifiers," they're usually talking about stereo components or musical equipment. But this is only a small representation of the spectrum of audio amplifiers. There are actually amplifiers all around us. You'll find them in televisions, computers, portable CD players and ...
There are holograms on most driver's licenses, ID cards and credit cards. If you're not old enough to drive or use credit, you can still find holograms around your home. They're part of CD, DVD and software packaging, as well as just about everything sold as "official merchandise...
That world is the field of nanotechnology, the realm of atoms and nanostructures. Nanotechnology is so new, no one is really sure what will come of it. Even so, predictions range from the ability to reproduce things like diamonds and food to the world being devoured by self-replicating...
Mass percentage is one of the best ways to express the concentration of a dissolved substance in a solution. Mass percentage refers to the ratio (expressed in percentages) of a mass of a compound in the solution to the total mass of the solution.
A physicist explains why mass is both well-defined and also a bit complicated, especially as the masses get really minuscule.
The molar mass, or sometimes called atomic mass or molecular weight, is defined to be the mass of a particular element or compound over 1 mole of the substance. It can be obtained from this definition or by taking the sum of the mass of atoms composing a compound. Molar mass is ...

or the average mass, in a group of atoms. However, electrons have so much less mass than protons and neutrons that they don't factor into the calculation. So, the atomic mass is the sum of the masses of protons and neutrons. For those learning how to calculate atomic mass, here ...
