The ratio of neutrons to protons in stable atomic nuclei ranges from about 1 to 1 at the lower end of the scale of atomic numbers to about 1.6 to 1 at the upper end. This band of stabilitymight also be called the stability belt, stability band, or stability zone, depending on the text being consulted. In general, any ratio that falls outside the band will represent an unstable nucleus, and that atom will be a radionuclide, and be radioactive, and will decay in time. Links can be found below.

In fact all the others have a ratio of 1 or more, except for helium-3 (its ratio is 1/2). For lower atomic numbers the ratio is often 1 (one neutron per proton) - this is true for the main isotopes of elements 2 (helium), 6 (carbon), 7 (nitrogen), 8 (oxygen) and 10 (neon). Others have just one more neutron than proton - elements 3, 4, 5, 9 and 11. As you increase the atomic number the ratio gradually increases. The last stable isotope is lead-208. Its ratio is just over 1.5.

What is the mass of an electron compared to the mass of a proton or neutron?
Mass ratio proton (neutron)/electron: 1 836
How many times is proton heavier than electron?
The ratio of a proton's rest mass to an electron's rest mass is 1836.15267247:1. For more information, follow the link below.
What happens if a free electron and a free proton are put into an electric field?
The proton will have greater acceleration. This is because the proton has a higher charge to mass ratio than the alpha particle. The proton has a +1 charge, as you know, and the alpha particle has a +2 charge because it has 2 protons in it. But the alpha particle also has a pair of neutrons fuesed to those 2 protons, so it has a 2 to 4 charge to mass ratio. The proton, with its 1 to 1 ratio of charge to mass, will have a greater acceleration in the same electric field.

Neutron/Proton Ratio
Charge-to-mass ratio of an electron?
Proton Mass, m = 1.67x10-27 kg Proton Charge, q = 1.6x10-19 C m/q = 1.04x10-8 kg C-1

calculate the ratio between proton&electron
What is the ratio r proton /r electron of the radii of their circular paths?
The ratio between radius of proton to the radius of electron is just 0.3
How does the mass of a electron compare to the mass of a proton and neutron?
Mass ratio proton (neutron)/electron: 1 836
How does the mass of a proton compare to the mass of a neutron and an electron?

What is the mass of an electron compared to the mass of a proton or neutron?

Why atom is neutral particle?
Because proton and nelutron present in nucleus with charges positive and negative while neutron have no charge and proton and electron have same in numbers and the ratio have between electron and is zero. For.eg magnesium have 12 atomic number and proton and are also 12 in magnesium there ratio is 1:1
In the electron charge to mass experiment if the electron is replaced by a proton or neutron would the charge to mass ratio value still be the same why or why not?
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.
What is the ratio of the mass proton to the mass of an ELECTRON?
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%.
How much more massive is a proton compared to a electron?
By sheer size, I would assume MUCH larger. But through weight, the proton is much heavier compared to an electron. On any element, the atomic number is the weight of the nuetrons and protons. The weight of electrons is so small and insignificant, it is usual not looked on at the highschool level. And has no effect on the molar mass.
What is the ratio of a proton to the mass of a neutron?
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.
How does mass of an electron compare to the mass of protons and neutrons?
Mass ratio proton (neutron)/electron: 1 836
How does the mass of an electron compare to the mass of a proton and neutron?
The proton mass is about 2,000 times greater than the electron mass.
