## What is the charge and mass of a particles?

The charge of an -particle is. 2 × 10 – 19 C (2 times the charge of a proton). The mass of an -particle is. 68 × 10 – 27 kg (4 times the mass of a proton).

## What is the symbol of beta particle?

A beta particle (β) is a high-speed electron emitted from the nucleus of an atom during some kinds of radioactive decay (see Figure 11.4. 2). The symbol for a beta particle in an equation is either β or e−01.

## What is mass of a gamma particle?

Gamma rays (γ) are not particles with a mass. They are a kind of electromagnetic radiation that is considerably higher in energy than x-rays. As a form of energy, gamma rays have no size or mass.

## What is the mass and charge of proton?

Proton is the positively charged particle present in the nucleus of the atom. Magnitude of charge: Charge of proton is 1.6022 x 10-19 coulomb. Mass of proton: Mass of proton is 1.0072766 a.m.u. or 1.6726 x 10-27 kg.

## What is a mass of proton?

What is the Mass of Proton? The mass of a proton is 1.6726219 × 10-27 kilograms. Protons are positively charged particles, electrons are negatively charged and neutrons have no charge. In an atom the number of protons and electrons are equal.

## What is charge of a proton?

A proton is one of three main particles that make up the atom. Protons are found in the nucleus of the atom. This is a tiny, dense region at the center of the atom. Protons have a positive electrical charge of one (+1) and a mass of 1 atomic mass unit (amu), which is about 1.67×10−27 kilograms.

## What is the mass number of beta plus?

The process is called “annihilation.” The rest mass of the positron (β+-particle) is 0.51 MeV/c2, equal to the rest mass of the electron, so 2×0.51 MeV energy is emitted in the annihilation process.
