Their masses are equal. It's their charges that are opposite.

Are the rest mass of the positron and the electron exactly equal?
Yes; they simply have opposite charges.
How is a positron different from an electron?
A positron is an electron's antiparticle. It has the same mass as an electron, but an opposite electrical charge.
The rest mass energy of an electron positron pair is?
Twice the mass of the electron, since the positron has the same mass of the electron. Or the equivalent, in energy units.An electron has a mass or energy of 511 keV.
Is The Mass Of An Electron Is Equal To The Mass Of A Neutrons?
No. The mass of a neutron is far, far, far greater than the mass of an electron. In fact, the mass of a neutron is approximately about 1840 times greater than the mass of an electron. The particle that has exactly the same mass as an electron is its antiparticle, the positron.
What is the mass number of a positron?
The mass of a positron is approximately 9.1093826(16) × 10−31 kg. The positron and the electron are anti-particles of each other, and you can find out more about the positron at the Wikipedia article on that subject. A link to their post can be found below. There is also a link to a related question on the nature of the positron. That's down there, too.
Do positrons are similar to electrons?
It's all quite simple. The electron is a subatomic particle carrying a negative electric charge. It has no known components or substructure, and therefore is believed to be an elementary particle.[2] An electron has a mass that is approximately 1/1836 that of the proton. The positron or antielectron is the antiparticle or the antimatter counterpart of the electron. The positron has an electric charge of +1e, a spin of 1⁄2, and the same mass as an electron.
What is a particle with a positive chatge?
A beta particle is an electron, and electrons are negative. You're probably thinking of a positron, which has the same mass as an electron but the opposite charge.
What would happen if a positron met an electron?
When a positron meets an electron, they annihilate or destroy each other.This phenomena is known as annihilation of matter. During this process two photons of gamma rays are produced that travel in opposite directions.Actually the mass of electron and positron has been converted into energy (gamma rays).
Why you need 1.022 Mev in pair?
Pair production can only occur if the energy of the photon is bigger than the rest mass (E0 = m0*c^2) of electron and positron, because this is the energy needed to create these particle (conservation of energy). Excess energy will be kinetic energy of the electron and positron. Rest mass of electron and positron is 0.511 MeV each, so 1.022 MeV in total.
What decay decreases atomic mass by 1?
Beta with a decay of a positron (as opposed to the more common electron).
What are positive electrons in science?
A positive electron is called a positron and it is a form of antimatter. It has the same mass and typical properties as a normal electron, but it has the opposite charge.
Is a proton the opposite of a electron?
No. The opposite of an electron is an antielectron or positron, which has exactly the same mass but opposite charge. A proton has opposite charge from that of an electron, but it is about 1836 times more massive.
