Compare and contrast beta-minus and beta-plus decay.

Beta-minus: Neutron transforms into a proton, emits electron and antineutrino. | Beta-plus: Proton transforms into a neutron, emits positron and neutrino.

What are the key differences between alpha and beta decay?

Alpha: Emission of a helium nucleus, changes mass and atomic number significantly. | Beta: Emission of an electron or positron, changes only atomic number.

Compare neutrinos and antineutrinos.

Neutrinos: Emitted in beta-plus decay. | Antineutrinos: Emitted in beta-minus decay. Both are electrically neutral and have nearly zero mass.

Compare alpha particle and gamma ray.

Alpha particle: Consists of 2 protons and 2 neutrons, has mass and charge. | Gamma ray: Is a high-energy photon, massless and chargeless.

Compare electron and positron.

Electron: negatively charged particle emitted in beta-minus decay. | Positron: positively charged particle emitted in beta-plus decay.

What is alpha decay?

A nucleus emits an alpha particle (24He^4_2He), decreasing the atomic number by 2 and the mass number by 4.

What is beta-minus decay?

A neutron transforms into a proton, emitting an electron (e−e^-) and an antineutrino (vˉ\bar{v}), increasing the atomic number by 1, while the mass number remains the same.

What is beta-plus decay?

A proton transforms into a neutron, emitting a positron (e+e^+) and a neutrino (vv), decreasing the atomic number by 1, while the mass number remains the same.

What is gamma decay?

An excited nucleus releases energy by emitting a gamma ray photon (γ\gamma). The atomic number and mass number remain unchanged.

Define alpha particle.

A particle consisting of two protons and two neutrons, equivalent to a helium nucleus (He2+He^{2+}).

Define neutrino.

An electrically neutral particle with nearly zero mass, emitted in beta-plus decay.

What is radioactive decay?

The process where unstable atomic nuclei release energy and particles to become more stable.

What is an alpha particle?

A particle consisting of two protons and two neutrons, equivalent to a helium nucleus (mathrmHe2+mathrm{He}^{2+}).

What is a neutrino?

An electrically neutral particle with nearly zero mass, emitted in beta-plus decay.

What is a positron?

A particle with the same mass as an electron but with a positive charge, also known as an antielectron (e+e^{+} or β+\beta^{+}).

What is an antineutrino?

An electrically neutral particle with nearly zero mass, emitted in beta-minus decay.

What is a gamma ray?

A high-energy photon emitted by an excited nucleus during gamma decay (gammagamma).
