The mass of a proton and neutron are pretty close. So the ratio will be roughly 1 to 1 (or 1:1). The neutron is heavier and if memory serves it is exactly the mass of an electron heavier than a proton. Note it takes around 1820 electron to equal the mass of one proton.
Dunno, but the ratio of the mass of a proton to the mass of what prople think of as being an electron is approx 1980. I'd check that if I were you though. Probably OK to +- 5%.

The mass of a nucleus varies according to the atomic number (ie according to what element it is). For hydrogen , the simplest nucleus, the combined mass of the one proton and the one neutron would be equal in mass to 3672 electrons.
Mass number in chemistry is the number of nucleons in the nucleus. Nucleon is the common name for proton and neutron. In case of Sodium atom the mass number is 23. If it gets changed by adding one more neutron then it is an isotope which is used in medical field as a radio isotope to study about the blood flow.
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.
Mass ratio proton (neutron)/electron: 1 836
Mass ratio proton (neutron)/electron: 1 836
Mass ratio proton (neutron)/electron: 1 836
Compared to the (charge/mass) ratio of the electron:-- The (charge/mass) ratio of the proton is much smaller; although the proton charge is equal to the electron charge, the proton mass is much larger, by a factor of more than 1,800.-- The (charge/mass) ratio of the neutron is zero, because the neutron charge is zero.
Mass of a Proton = 1.6726x10-27 kg Mass of a Neutron = 1.6749x10-27 kg The ratio is then: 0.99864
Neutron/Proton Ratio
the neutral or no charge particle of an atom:it is located in the nucleus;has the same mass as the proton.
Mass ratio proton (neutron)/electron: 1 836
Stability depends on to proton/neutron ratio; and this ratio increase with the atomic number.
The mass of a proton is equal to a neutron.
If a proton would be 1, an electron would be 0.000544. An electron is 1,836 times lighter than a proton. A neutron would be 1.001 as a proton is 99.86% the mass of a neutron
The proton mass is about 2,000 times greater than the electron mass.
