The decreasing order (highest first) from the values of

{e} / {m}

(charge/mass) for electron

(e),

proton

(p)

, neutron

(n)

and alpha particle

(\alpha)

is

View answer and explanation

Correct option: A

e, p, \alpha, n

Option A is correct because the charge-to-mass ratio (e/m) decreases in the order: electron > proton > alpha particle > neutron.
