Alpha, Beta, and Gamma Radiation - IB Physics

During Beta decay, if the substance (not an ione) is losing an electron and also gaining a proton, shouldnt the charge of the substance be +2?

Thank you so much sir! You are a blessing in disguise

Very nice explanation, thank you so much sir, keep doing more videos please

For the radiation in magnetic fields, isn't it the left hand rule since we're determining the force on on a current carrying conductor in a magnetic field, not the direction of induced current in a generator? I'm not sure, since right hand rule doesn't yield the correct direction for force for me, but left hand rule does.
