Proton mass = approx. 1,850 x electron mass.
If volumes are similar, then proton density = approx. 1,850 x electron density.
The four inner, terrestrial or rocky planets all have similar densities, much higher than the four outer gas giant planets (though the outer planets are much larger and more massive).

Nothing is identical to an electron as electrons obey the Pauli exclusion principle and they are all different. == Another electron. All electrons have the same elemental structure. Certainly when we evaluate them in "small regions" of space, their momentum is uncertain. But intrinsically, all electrons are alike. And somewhere there is footage of Murray Gell-Mann saying exactly that. He has a pretty good grip on stuff like this. The Nobel Prize he won in Physics is just icing on the cake.
Indistinguishable particles are particles that are so similar or identical that they can not be distinguished from another. Electrons and sometimes atoms and molecules can be indistinguishable particles.
The Similar is something i dont know
The electron is the smallest of the three main atomic particles by a long way. The proton and neutron are of a similar size, with the neutron having (very) slightly more mass. The mass of an electron is around 1/1840 of a proton or electron.
As a rule of thumb ... which is not true in all cases ... the solid and liquid states will have similar densities with the liquid being the less dense of the two, and the density of the gas will be much lower.Near the critical point the density of the liquid and gas phases will be nearly identical.
An Alpha Particle is a fast, bare Helium nuclei composed of two protons, two neutrons, and no electrons, that is ejected at high velocity from a decaying nuclei. A Beta Particle is an electron or positron, ejected at extremely high velocity from a decaying nuclei. Both alpha particles and protons are Bosons. Both beta particles and electrons are Leptons. Their relationships are similar because the electron and proton are both components of atoms. The beta and alpha particles are both fragments ejected from decaying atoms.

They are virtually identical with very similar densities.
The mass of a neutron is approx 1837 times that of an electron. The mass of a proton is similar to that of a neutron. In the simplest atom, hydrogen, the mass of the nucleus is 1,837 times that of an electron. In the largest known atom, that of ununoctium, containing 281 baryons (neutrons or protons) the mass of the nucleus is approx 516,200 times that of an electron. So take your pick: 1,837 to 516,200.

You can compare similar fractions by looking at their numerators. You can compare dissimilar fractions by converting them to similar fractions and looking at their numerators. You can convert a dissimilar fraction to a similar fraction by finding the least common denominator.
Because they have similar electron configurations.

For beta- decay, the resulting particles are an electron and an antineutrino. However, it is incorrect to say that these particles create the beta particle. It is more correct to say that the weak interaction causes a down quark in a neutron to change to an up quark, releasing a W- boson. The neutron becomes a proton, and the W- boson decays into the electron and the antineutrino. For beta+ decay, the resulting particles are a positron and a neutrino. It is a similar, though not quite the same reaction. Energy is absorbed, either from an energy rich nucleus, from electron capture, or from internal conversion, converting an up quark in a proton into a down quark, releasing the positron and neutrino, and changing the proton into a neutron.
