Which statement(s) correctly compare the masses of protons, neutrons, and electrons?
check all that apply.
__protons and neutrons have similar mass.
__protons and electrons have similar mass.
__neutrons and electrons have similar mass.
__protons are smaller than a neutron or an electron.
__neutrons are smaller than a proton or an electron.
__electrons are smaller than a proton or a neutron.

__Protons and neutrons have similar mass.  

__Electrons are smaller than a proton or a neutron.

Explanation:

As we know that the masses of proton electron and neutron is given as

so here we can say that electron is of least mass among all three

and also we can see that protons and neutrons are of similar mass range

in more microscopic way if we see them then neutrons are slightly heavier than the proton

so correct answer would be

__Protons and neutrons have similar mass.  

__Electrons are smaller than a proton or a neutron.
