It is a natural law; I suppose that any rational explanation is possible.
Mass ratio proton (neutron)/electron: 1 836
Mass ratio proton (neutron)/electron: 1 836
Mass ratio proton (neutron)/electron: 1 836
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 neutral or no charge particle of an atom:it is located in the nucleus;has the same mass as the proton.
The electron is the smallest having about 1/1836th the mass of a proton or neutron, which means that basically an electron has no mass. The neutron and proton weigh the same both having a mass of 1.
neutrons and protonsbut NOT electrons (the almost have no mass)
1 proton and 1 neutron is needed because the 2 in hydrogen 2 refers to the atomic mass and protons and neutron have a mass of about 2 daltons each.
The proton an neutron both have a mass of about 1 amu. (Both have a mass just slightly above 1 amu, and the neutron's mass is slightly larger than that of a proton.)
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.
The mass number of a neutron is 1, as it contains one unit of mass. The mass number of a proton is also 1, as it contains one unit of mass. In hydrogen, the nucleus usually consists of one proton, so the mass number of a proton in hydrogen is 1.
Commonly considered to be a neutron. However the true mass of a neutron is slightly higher than the combined mass of a proton and an electron.
