Alpha particle is a helium nucleus that comprises two protons and two neutrons, and the charge is twice the charge of the proton while the mass is around four times greater. Mass of helium = 4m. Therefore, the charge to mass ratio of an alpha particle is approximate twice the charge to mass ratio of a proton.
What is the relation between mass of proton electron and alpha particle?
Let mass of proton be m which is equal to approximate 1.6*10^-27 kg and as alpha particle consists of two protons and two neutrons and mass of proton and neutron is quite similar so mass of alpha particle will be equal to four times of mass of proton i.e. 4m whereas mass of electron is around 1900 times lighter than …
Is an alpha particle the same as a proton?
Alpha particles are relatively slow and heavy compared with other forms of nuclear radiation. The particles travel at 5 to 7 % of the speed of light or 20,000,000 metres per second and has a mass approximately equivalent to 4 protons.
What is the relation between alpha particle and electron?
1 Answer. The alpha particle is 7294 times as massive as an electron.
Why is the mass of alpha particle 4 times proton?
Hint: An alpha particle is actually a helium nucleus which consists of two protons and two neutrons so its charge is twice the proton's charge and the mass is four times greater. Hence the charge to mass ratio of an alpha particle is twice the charge to mass ratio of a proton.
What is relation between proton and electron?
Electron vs Proton
| Electron | Proton |
|---|---|
| It requires less amount of energy to be removed from the atom. | It requires a lot of energy to be removed from the atom. |
| It is represented by the symbol “e”. | It is represented by the symbol “p”. |
| The mass of an electron is 9.1 × 10-31 Kg. | The mass of a proton is 1.67 × 10-27 Kg. |

What is relation between mass of proton and electron?
proton, stable subatomic particle that has a positive charge equal in magnitude to a unit of electron charge and a rest mass of 1.67262 × 10−27 kg, which is 1,836 times the mass of an electron.
Which is more positive proton or alpha particle?
Alpha particle is a helium nucleus so it has more power compare to proton. It charge has +2E, which is twice of a proton.
What happens alpha particles?
When an atom emits an alpha particle in alpha decay, the atom's mass number decreases by four due to the loss of the four nucleons in the alpha particle. The atomic number of the atom goes down by two, as a result of the loss of two protons – the atom becomes a new element.
Which is larger a proton or an electron?
Atomic particles Protons and neutrons have approximately the same mass. However, one proton is about 1,835 times more massive than an electron.
