What difference is between Beta particle and negative charges?

In summary, beta particles are high-energy, high-speed electrons or positrons emitted by certain types of radioactive nuclei such as potassium-40. They are a form of ionizing radiation also known as beta rays. These particles are harmful to human health as they have the ability to damage the body at a sub-cellular level. They are similar to high-speed bullets that cannot be seen and do not leave visible wounds. Thank you to everyone for their suggestions.

"Beta particles are high-energy, high-speed electrons or positrons emitted by certain types of radioactive nuclei such as potassium-40. The beta particles emitted are a form of ionizing radiation also known as beta rays. "

Negative charges also contain electrons, Beta particle are high-energy, high-speed electrons.
What make beta particle harmful to human? will high-speed electrons be the main cause?
Does anyone have any suggestions?
Thanks in advance for any suggestions

Just a question, but are you just trying to get people to do your homework for you?

Beta particles are electrons, they're just electrons that originate from nuclear reactions, decays, etc., so we call them beta particles instead.

They're like a lot of high speed bullets fired at your body.
Except that they don't leave wounds, and you can't see them, but they damage the body at a sub-cellular level.

1. What is a Beta particle?

A Beta particle is a high-speed electron or positron that is emitted from the nucleus of an atom during radioactive decay. It has a negative charge and a mass of approximately 1/1837 of a proton.

2. How is a Beta particle different from a negative charge?

A Beta particle is a specific type of negative charge that is emitted from the nucleus of an atom during radioactive decay. It is a moving particle with a specific mass and charge, whereas a negative charge can refer to any negatively charged particle or object.

3. What is the origin of Beta particles and negative charges?

Beta particles are formed during the decay of a neutron into a proton, electron, and antineutrino. Negative charges can originate from a variety of sources, including electrons, ions, and other particles that have gained or lost electrons.

4. How can Beta particles and negative charges be detected?

Beta particles can be detected using instruments such as Geiger counters or scintillation detectors, which can measure the amount and energy of the particles. Negative charges can be detected through their interaction with electric and magnetic fields, or by measuring the electrical current they produce.

5. What are the effects of Beta particles and negative charges on matter?

Beta particles can ionize matter, meaning they can knock electrons off atoms as they pass through, which can cause damage to living cells and materials. Negative charges can also cause ionization and can attract or repel other charged particles, leading to various effects on matter and its behavior.
