The charge/mass ratio for an alpha particle is 4.82245111 x 107 C/kg.


Charge of alpha particle = 2e = 2 x 1.602176487×10−19 C = 3.20435297 ×10−19 C

Mass of alpha particle = 6.64465620×10−27 kg

Why do alpha and beta rays deflect in an opposite direction?

Alpha particles deflect backwards due to repulsive electrostatic force between the particles and nucleus. They are all charged positively (like charges repel), hence the repulsive electrostatic force


Why are radioactive elements which emit alpha particles more dangerous outside the body than inside?

It is the opposite. Radioactive elements which emit alpha particles are more dangerous inside the body than outside. Alpha particle radiation could be stopped by skin. So, is not dangerous outside the body. However, any contamination by those radioactive elements if got inside through mouth, or any other means, then the alpha particle radiation could be harmful to the very delicate inside body tissues.


What is the equation for alpha decay of Thorium?

232Th --> 228Ra + 4He 228Ra --> 228Ac + e- 228Ac --> 228Th + e- 228Th --> 224Ra + 4He 224Ra --> 220Rn + 4He 220Rn --> 216Po + 4He 216Po --> 212Pb + 4He 212Pb --> 212Bi + e- 212Bi --> 208Tl + 4He, 212Po + e- 208Tl --> 208Pb + e- 212Po --> 208Pb + 4He 208Pb, stable Other isotopes of Thorium undergo beta decay, but they are not naturally occurring.


What happens to an atom's mass number when it ejects an alpha particle?

An alpha particle is essentially a 4He nucleus, 2 protons and 2 neutrons, one of the most stable configurations of protons and neutrons possible. So if an atom spits out 2 protons and 2 neutrons in an alpha particle, it must lose 2 protons and 2 neutrons from its own particle count. If you consider that the mass number is just the sum of protons and neutrons, then you can see that the mass number will simply decrease by 4. However what's really interesting is that in general, the mass (not mass number) of the atom decreases by just a little more than the mass of 2 protons and 2 neutrons. That missing mass goes into the famous E=mc2 equation to be the energy with which the alpha particle leaves (also some energy will be in the recoil of the nucleus emitting it, but for heavy atoms usually this is fairly small.)

What is the nuclear decay equation for an example of alpha decay?

There are a number of radioactive isotopes of copper, choosing 66Cu as on that undergoes negative beta decay, the equation is: 2966Cu --> 3066Zn + -10e Where e represents the beta particle, which can also be viewed as an electron.


What is the nuclear equation for the alpha decay of 242 Pu?

Plutonium-241 decays by both beta- and alpha decay. For beta- decay the equation is ...94241Pu -> 95241Am + e- + v-eNot asked but answered for completeness sake, for alpha decay the equation is ...94241Pu -> 92237U +24He2+


How in electron e upon m ratio remain always same in contrary to protons?

Because its mass and charge are constant.

What is the nuclear decay equation for uranium-238 to strontium-90?

The equation for the beta decay of 87Kr is: 3687Kr --> 3787Rb + -10e where -10e represents a negative beta particle or electron.


What radioactive decay would uranium...238 be if it undergoes alpha then beta then beta then beta then alpha then alpha?

238U --> 234Th + 4He 234Th --> 234Pa + e- 234Pa --> 234U + e- 234U --> 234Np + e-, not possible


What is the nuclear reaction for alpha decay of Radium-226?

Since an alpha particle is a helium-4 nucleus, the resulting atom has an atomic mass that is 4 less, so 226 minus 4. Also, to get the element, look up the element number for radium, and subtract two from that.


Is a high P E ratio better than a low P E ratio?

No. A higher P E ratio can result in much better results than a lower P E ratio, but it is a lot riskier. Meaning a higher risk of loss for the higher P E ratio.
