# What Is Beta Decay With Example

## What is beta decay with example?

Beta decay is a radioactive decay in which a beta ray is emitted from an atomic nucleus. During beta decay, the proton in the nucleus is transformed into a neutron and vice versa. If a proton is converted to a neutron, it is known as β+ decay. Similarly, if a neutron is converted to a proton, it is known as β– decay.

## How do you write a decay equation?

1. Step 1: Identify the element, its atomic mass and atomic number given in the problem. …
2. Step 2: Identify the type of radioactive decay.
3. Step 3: Write the element with the atomic mass and the atomic number on the left side of the equation.

## What is the equation for positron decay?

Positron decay is characterized by the following decay equation using 18F as an example. F → 18O + β+ + υ β+ is the positron, and υ is a neutrino, a particle with no mass or charge that always accompanies the positron in the decay process due to conservation of energy requirements.

## What is the equation for alpha decay?

A general equation for this type of alpha decay radiation is: Z A X → Z − 2 Z − 4 Y + 2 4 He . An example of alpha decay is when uranium-238 gives off an alpha particle and produces thorium-234.

## What are the 3 types of beta decay?

Two types of beta decay can occur. One type (positive beta decay) releases a positively charged beta particle called a positron, and a neutrino; the other type (negative beta decay) releases a negatively charged beta particle called an electron, and an antineutrino.

## What is beta decay easy?

Beta decay occurs when, in a nucleus with too many protons or too many neutrons, one of the protons or neutrons is transformed into the other. In beta minus decay, a neutron decays into a proton, an electron, and an antineutrino: n Æ p + e – +.

## What is beta decay in chemistry?

beta decay, any of three processes of radioactive disintegration by which some unstable atomic nuclei spontaneously dissipate excess energy and undergo a change of one unit of positive charge without any change in mass number.

## What is the symbol for beta decay?

Beta particles (β) are high energy, high speed electrons (β-) or positrons (β+) that are ejected from the nucleus by some radionuclides during a form of radioactive decay called beta-decay. Beta-decay normally occurs in nuclei that have too many neutrons to achieve stability.

## What is alpha and beta decay?

Alpha decay – A common mode of radioactive decay in which a nucleus emits an alpha particle (a helium-4 nucleus). Beta decay – A common mode of radioactive decay in which a nucleus emits beta particles. The daughter nucleus will have a higher atomic number than the original nucleus.

## What is the beta plus decay?

Positron emission, beta plus decay, or β+ decay is a subtype of radioactive decay called beta decay, in which a proton inside a radionuclide nucleus is converted into a neutron while releasing a positron and an electron neutrino (νe). Positron emission is mediated by the weak force.

## What is beta decay plus?

During beta-plus decay, a proton in an atom’s nucleus turns into a neutron, a positron and a neutrino. The positron and neutrino fly away from the nucleus, which now has one less proton than it started with. Since an atom loses a proton during beta-plus decay, it changes from one element to another.

## What is an example of a gamma decay?

Gamma Decay Example The examples of gamma decay are mentioned as follows: The gamma decay of Barium-137 in which the level of energy lowers. The element Barium-137 loses its spin as well as dissipates its energy and becomes stable from its unstable state.

## What is beta decay called?

In beta minus (β−) decay, a neutron is converted to a proton, and the process creates an electron and an electron antineutrino; while in beta plus (β+) decay, a proton is converted to a neutron and the process creates a positron and an electron neutrino. β+ decay is also known as positron emission.

## What is a real life example of beta decay?

Elements that have beta decay can have useful medical applications. Radionuclide therapy (RNT) or radiotherapy is a cancer treatment that uses beta decay. In this process, lutetium-177 or yttrium-90 is attached to a molecule and ingested. Once inside the body, this molecule travels to the cancer cells.

## What is alpha decay with example?

Alpha decay. An example of this decay occurs in the uranium-238 nucleus that decays into thorium-234 nucleus. Alpha particle has a relatively large mass, positive electric charge, and poor radiation penetration, and it can be stopped by a paper sheet (Ilem-Ozdemir and Asikoglu, 2012).
