Yes alpha particles are matter. In fact they are just the nuclei of Helium atoms. That is Helium atoms without their two orbiting electrons. Alpha particles are therefore composed of two neutrons and two protons.

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.
Are the atoms in the gold foil experiment a positive or negative charge?
Positively charged atoms, In Rutherford's experiment he bombarded an extremely thin piece of gold foil with alpha particles. Alpha particles are tiny, high energy, positively charged particles.
What does ionization mean?
Alpha particles have a big mass and a charge of +2. The positive charge means they cause lots of ionization in a short distance. Each time the alpha particle rips an electron off a molecule it loses some energy and slows down a bit. An alpha particle might make 100 000 ionizations before it loses all its energy. It grabs two electrons and becomes a helium atom. An alpha particle will ionize most air molecules it passes close to, which is why it loses energy so quickly and has a short range in air. This is why the cloud trails are short and fat. The alpha particle has quite a big mass. So it's difficult to change its direction. This makes the path straight.

Alpha particles and beta particles differ in?
Alpha particles are positively charged helium nuclei while beta particle are negatively charged electrons . Alpha particle have 4u mass while beta particles have zero mass.
What are alpha particles used for?
We commonly see an isotope of americium generating alpha particles to ionize air in smoke detectors. A source generates alpha particles to ionize air in industrial settings so that the ionized air will quickly and effectively dissipate static charges. A radio pharmaceutical generates alpha particles, and the unsealed source irradiates tumors in patients that are so implanted. We find alpha particle sources in the physics lab where they are used in experiments and demonstrations. Alpha particles can be accelerated for use as "atomic bullets" in high energy physics research.
Beta particles cannot penetrate very far into solids because they..have low velocity have negligible mass have no mass are confined to orbits?
Beta particles cannot penetrate very far into solids because they...HAVE NO MASS and HAVE HIGH VELOCITY.
Why alpha particles tend to produce more ions than beta particles or gamma rays when they pass through matter?
Alpha particles have a high ionizing power beacaue they have a great linear transfer of energy.
What is alpha ionizing?
Alpha particles are helium nuclei emitted with energies of several MeV and travelling at about 5% speed of light. As air molecules take only about 35eV to ionize, highly charged alpha particles are very strongly ionizing.

Why alpha particle exhibit definite range in matter?
because alpha particles are charged.
How would you list alpha particles beta particles and gamma rays in order of increasing energy?
Alpha, beta, gamma.
Are alpha particles the most penetrating?
No. Alpha particles, consisting of 2 protons and 2 neutrons - effectively a Helium nucleus - are very heavy (for a decay particle) and readily ionize surface materials. For this reason, they have very low penetration.Alpha particles are not the most penetrating, instead it is the Gamma rays that penetrate better.

Differentiate gamma rays from alpha particles?
Gamma rays are very high energy Photons. Whereas, alpha particles are Helium nuclei.
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.
What is delta radiation?
Delta rays very fast electrons produced in quantity by alpha particles or other fast energetic charged particles knocking orbiting electrons out of atoms. Collectively, these electrons are defined as delta radiation when they have sufficient energy to ionize further atoms through subsequent interactions on their own.P. Stewart
