To conserve energy in beta decay.
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.
No, a neutron is slightly more massive than a proton. Both particles have roughly the same mass, but due to the different composition of their internal quarks, the neutron is slightly heavier.
The neutron has a mass that is nearly equal to the combined mass of a proton and an electron. This is due to the fact that the neutron is slightly heavier than the proton, while the electron has a much smaller mass.
No, the designations of hydrogen for the proton and neutron for the neutron do not imply that these two particles are of equal mass. A proton is about 1836 times heavier than a neutron. The terms "hydrogen" and "neutron" were historically used to describe these particles based on their properties and roles in atomic structure, rather than their masses.
Tritium is lighter than deuterium. Tritium is a hydrogen isotope with one proton and two neutrons, making it heavier than regular hydrogen but lighter than deuterium, which has one proton and one neutron.
Because proton and neutron are in about one thousand times heavier than electron.
Because proton and neutron are in about one thousand times heavier than electron.
Protium, deuterium, and tritium are all isotopes of hydrogen (H). As far as their masses: Tritium>Deuterium>Protium In their nuclei: Protium has 1 proton and 0 neutrons Deuterium has 1 proton and 1 neutron Tritium has 1 proton and 2 neutrons So yes, Deuterium is heavier than tritium.
The neutron has slightly more mass than a proton. Both are usually rounded off to a mass of 1 amu but the neutron is just a little heavier (about 1/1800 th heavier)
an electron is much lighter than a proton or neutron.
Tritium is heavier than deuterium. Tritium consists of one proton and two neutrons, while deuterium consists of one proton and one neutron. Because tritium has an extra neutron, it is heavier than deuterium.
The neutron is 0.16% larger than a proton.
