When trying to find the number of neutrons, protons or electrons that different chemical species have, the periodic table is your best friend. Take a look at how to use the periodic table as well as nuclear notation to find the number of subatomic particles associated with any chemical species...
To find the number of neutrons in an isotope, find the mass number of the isotope and the atomic number. The atomic number, or number of protons, is found on the Periodic Table. The atomic mass, also found on the Periodic Table, is the weighted average of all the isotopes of the ...
The amount of energy in a light wave is proportionally related to its wavelength: shorter wavelengths have higher energy. Of visible light, violet has the most energy and red the least. Just above the visible light spectrum is ultraviolet (UV) light, and it turns out that natural sunlight ...

Neutrons are neutrally charged subatomic particles found in the nucleus of an atom along with the positively charged protons. Together, protons and neutrons contribute equally to the mass number of the atom. Answer and Explanation:1 Calculating the number of neutrons in the nucleus of an a...
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...
Gamma-ray bursts are observed occurring all across the sky at a rate of about one per day, though their true number is probably much larger. If one were to occur close to Earth, say in the Milky Way, and its beam was directed toward Earth, our entire planet could be sterilized. And ...

The rare radioactive metal is manufactured at a nuclear reactor elsewhere by bombarding bismuth-209 with neutrons, but has to be extracted in the laboratories at VNIIEF. It is used commercially in miniscule amounts in devices that remove static from sensitive environments that ...
Question: How to compute/create a tangent portfolio? Answer and Explanation: A tangent portfolio is one that that obtains the highest possible sharp ratio, which gives it the best relative performance in terms of risk. The way... Learn more about this topic: ...
