Physics Teaching is my EXPERTISE with assured improvement
Alpha particle
is 2He4
it has Charge of 2 protons
and mass = 2 Protons + 2 neutrons
Q = 2* Charge of proton = 2* 1.602 *10 -19 C = 3.204 *10 - 19 C
M = 4 * 1.67*10 -27 = 668 * 10-27 Kg
I have used mass of proton and neutron nearly the same ( approx)
