Which of the following shows an increasing value of   |e/m| ?

A)n

B) n< p< alpha

C) n < p < e< alpha

D) p < n < alpha < e

i have no idea what this question means, and why is alpha particle even here....pls can someone explain clearly!

Hi Rosala,

The (e/m) ratio ascends in this order:  n < α < p < e (neutron, alpha particle, proton, and electron)

The neutron does not have a charge, so the value is zero. An alpha particle is a helium nucleus (2 protons, 2 neutrons); it is very heavy compared to the other particles. The proton and electron are next. The proton has the same charge as an electron but it is 1837 times heaver.
