What is the velocity of beta particle?

Beta particles have a mass which is half of one thousandth of the mass of a proton and carry either a single negative (electron) or positive (positron) charge. As they have a small mass and can be released with high energy, they can reach relativistic speeds (close to the speed of light).

Is the alpha particle the fastest?

Alpha, Beta, Gamma in ascending order. Alpha particles leaves the nucleus of an unstable atom at a speed of 16,000 kilometres per second, around a tenth the speed of light. Beta particles travel at a speed of 270,000 kilometres per second, around 98\% of speed of light. Gamma particles travel at the speed of light.

What is velocity of alpha particle that travel towards the nucleus?

We know that charge of an alpha particle is $2 \times 1.6 \times {10^{ – 19}}C$. The velocity at which the $\alpha – $particle travel towards the nucleus of a Cu atom to reach at a distance of ${10^{ – 13}}m$ is $6.3 \times {10^6}m{\sec ^{ – 1}}$.

What is alpha and beta particle?

Alpha denotes the largest particle, and it penetrates the least. Alpha particles carry a positive charge, beta particles carry a negative charge, and gamma rays are neutral. An alpha particle is made up of two protons and two neutrons bound together. Beta particles are high energy electrons.

How do you find the speed of an alpha particle?

1. You can calculate the speed of the alpha particle by knowing the mass of the original nucleus and the mass of the final nucleus.
2. Mass of parent nucleus – ( mass of daughter nucleus+mass of alpha particle) = mass defect.
3. You need to have the amount of missing mass , the mass defect expressed in kg.

How do you calculate alpha particle emitted?

So first look at the father nucleus and list its number of protons and its atomic weight. Step 3) Now from number of neutrons subtract 2 and from number of protons subtract 2 as an alpha particle has 2 neutrons and 2 protons and in an alpha decay an alpha particle will always form in case of any any father nucleus.

When proton and alpha particle are moving with same velocity then ratio of their de Broglie?

If debroglie wavelength of proton and alpha particle are equal then ratio of their velocities are. m is mass and v is velocity. By equating momentum for Both we can easily find that velocity of Proton will be four times that of Alpha particle Because alpha particle is four times Heavies than that of Proton.

What are the uses of alpha particle?

Cancer Treatment. Alpha radiation is used to treat various forms of cancer. This process, called unsealed source radiotherapy, involves inserting tiny amounts of radium-226 into cancerous masses. The alpha particles destroy cancer cells but lack the penetrating ability to damage the surrounding healthy cells.

What is the formula for alpha particle?

Alpha particle. Alpha particles are named after the first letter in the Greek alphabet , α. The symbol for the alpha particle is α or α 2+. Because they are identical to helium nuclei, they are also sometimes written as He2+ or 4 2He2+ indicating a helium ion with a +2 charge (missing its two electrons).

How many electrons are in an alpha particle?

An Alpha particle consists of 2 protons and 2 neutrons. Since it doesn’t contain any electrons hence you can write +2 charge.

What are some examples of alpha particles?

Examples of this sort of nuclear transmutation are when uranium becomes thorium, or radium becomes radon gas, due to alpha decay. Alpha particles are commonly emitted by all of the larger radioactive nuclei such as uranium, thorium, actinium, and radium, as well as the transuranic elements.
