neutron
alpha particle
beta particle
proton
question 10
6 pts
which type of radiation is deflected towards the negative side of an electromagnetic field?
alpha
beta
gamma

Explanation:

For the first question: A beta particle is an electron ($_{-1}^0e$), but the given representation is $_{0}^{-1}e$ (swapped subscript and superscript relative to standard notation, though sometimes written with charge as superscript; the proton representation is missing the atomic number subscript: a proton is $_{1}^1p$, not $^1p$—this is the incorrect one. For the second question: Alpha particles have a +2 charge, so they are attracted to the negative side of an electromagnetic field. Beta particles are negative and attracted to positive; gamma is neutral.

Answer:

First question: proton $^1p$
Second question: alpha
