Why would electrons be useful for investigating the atomic structure of material? Why is the atomic theory important? Why is atomic physics important? Why an electron does not fall into the nucleus of the atom? Why is there a strong nuclear force between protons? Why is gravitational force in...
Why do radioactive isotopes emit radiation? Describe nuclear fusion Why do atomic nuclei decay? How does a cyclotron produce radioisotopes using hydrogen? Where does deuterium come from? Why is binding energy per nucleon constant? Why is Rutherford's model called the nuclear atom?
Ionizing radiation canremove electrons from the atoms, i.e. it can ionize atoms. What is ionizing radiation? Ionizing radiation is radiation with enough energy that to remove tightly bound electrons from the orbit of an atom, causing that atom to become charged or ionized. Why do gamma rays ...
Fission can be controlled easier, that is why it is used the most. fission occurs by splitting an atom, instead of putting two molecules by force at high speeds, and changing the atomic number of the molecule. Fusion needs some requirements to occur, it needs high pressure and high temperat...
Imagine an advanced alien civilization that develops some fantastical technology that would break our current conceptions of physics. Say that they use that technology to colonize star system after star system, hopping across the void and spreading their influence. Let’s say that they colonize and ...
According to the RIM model, this effect would lead to less efficient overlap between the vibrational wavefunctions of S11 and S00 and consequently a decrease of intramolecular nonradiative rates and enhancement of the emission quantum yields in the condensed phase. However, the experimental results ...
Find out all about these elusive ripples in space-time and why the latest detection has astronomers celebrating.
would happen and hence what to look for), we have to find other ways that strings interact with the Universe around them. There are many ways that strings can potentially couple to the Standard Model of particle physics: They might directly emit electromagnetic radiation, or they ...
How is the atomic mass of an atom calculated? Define relative atomic mass Why do atomic nuclei decay? Why does atomic radius change as it does? Why is the mass defect important in nuclear chemistry? Why would electrons be useful for investigating the atomic structure of material?
Why do atoms emit particular wavelengths of radiation, and not all wavelengths? Why does each different chemical element have its own characteristic spectrum? An x-ray photon is scattered by an electron. What happens to the frequency of the scattered photon relative to that of the incide...
