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
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
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.
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.
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.)

e- is the symbol for an electron, aka a beta particle. It has a unit negative charge.
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.
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+
Because its mass and charge are constant.

The equation for the beta decay of 87Kr is: 3687Kr --> 3787Rb + -10e where -10e represents a negative beta particle or electron.
238U --> 234Th + 4He 234Th --> 234Pa + e- 234Pa --> 234U + e- 234U --> 234Np + e-, not possible
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.
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.
