What else can I help you with?
What particles have very weak penetrating power?
Alpha particles have very weak penetrating power. They are heavy and charged, so they interact strongly with matter, causing ionization and losing energy quickly. Therefore, alpha particles can generally only travel a few centimeters in air and can be easily stopped by a sheet of paper or skin.
Which radioactive particle can be stopped by a regular sheet of notebook paper?
Alpha. Beta particles are blocked by a few mm of aluminum and gamma by a few cm of lead. Alpha. Beta particles are blocked by a few mm of aluminum and gamma by a few cm of lead.
What changes in a radioactive material to make it emit radiation?
Radioactive decay occurs when unstable atomic nuclei lose energy to become more stable. This process can involve emitting particles (such as alpha or beta particles) or electromagnetic radiation (such as gamma rays).
What forces Between the particles in a gas are weak?
the bonds between particles in a liquid are very weak
What is the weak force transmitted by?
The weak force is transmitted by a collection of mediating particles. These particles are designated Z's and W's. The Z is a photon made heavy.
What particles have very weak penetrating power?
Alpha particles have very weak penetrating power. They are heavy and charged, so they interact strongly with matter, causing ionization and losing energy quickly. Therefore, alpha particles can generally only travel a few centimeters in air and can be easily stopped by a sheet of paper or skin.
Which type of radioactive emission has a positive charge and weak penetrating power?
Alpha particles have a positive charge and weak penetrating power. They can be stopped by a sheet of paper or a few centimeters of air.
Which radioactive particle can be stopped by a regular sheet of notebook paper?
Alpha. Beta particles are blocked by a few mm of aluminum and gamma by a few cm of lead. Alpha. Beta particles are blocked by a few mm of aluminum and gamma by a few cm of lead.

Why are beta particles more penetrating than alpha particles?
Alpha particles have a mass of 4 amu and a charge of +2, while beta particles have a mass of 1/1800 amu and a charge of -1. As a result, alpha particles are much more likely than beta particles to interact with matter, making it very difficult for them to penetrate anything.Unfortunately, because of their high ionization (interaction) rate, alpha particles are more damaging when they are in close contact with sensitive tissues, such as when alpha emitting materials are ingested. They can be stopped with a few inches of air, a sheet of paper, or even your skin; but inhale or swallow the parent material, and all bets are off, sorry.
What forces Between the particles in a gas are weak?
the bonds between particles in a liquid are very weak
Does alpha decay affects the number of neutrons in an element?
WEAK
What is alfa waves?
Weak radiation waves. Spelled alpha btw. Anyway, when a radioactive substance decays alpha rays it is very weak radiation, not even enough to penetrate human skin.
Why can alpha keratin stretch?
I believe it is because of the alpha helix spiral structure of the molecule and the weak hydrogen bonds that create elasticity.
What does nuclear radiation have to do with how a smoke detector works?
A weak source of Americium-241 is found in smoke detectors. The Alpha particles, which ionise the air, are emitted from here. This causes the air to conduct electricity and a small current flows.
What is the weak force transmitted by?
The weak force is transmitted by a collection of mediating particles. These particles are designated Z's and W's. The Z is a photon made heavy.
What is the difference between an omega wolf and an alpha wolf?
Alpha: The Leader of the Pack. Omega: The lowest member of the Pack.
