Does an alpha particle undergo electromagnetic radiation?
Yes alpha particle goes under goes electromagnetic radiations. when an atom is exposed to the magnetic field the alpha particle deviates right through right direction which indicates does have capacity to excite and emits radiations to come to ground level.
How fast are alpha particles in water?
The "speed" of an alpha particle will be determined by what it is that generates that alpha particle. That's another way of saying that alpha particles, which are helium-4 nuclei, come in different energies. You will recall that they are generated in alpha decay, which is a form of radioactive decay. As to how "fast" they are in water, all we can state is an initial energy, and then do some calculations to determine how far they might go. As a sheet of notebook paper will stop an alpha particle, it will not travel very far in water. Small fractions of an inch is all we could expect for the distance they'd be able to go. Heck, they'd be bumping into water molecules right from the gate, and losing energy with each collision (which is called a scattering event). Links to related questions can be found below.
An alpha particle is identical to?
Alpha particle has same effect with gamma rays in photographic effect ,both can can blacken a photographic film.And it has same effect with beta particles in the effect of electric and magnetic fields, both are deflected by electric and magnetic fields.
What is released during alpha decay?
In beta- decay, a neutron is converted into a proton, and an electron and an electron antineutrino is emitted. More fundamentally, a down quark is converted into an up quark by the emission of a W- boson. The quark conversion is part of the neutron becoming a proton, and the W- boson subsequently decays into the electron and electron antineutrino.In beta+ decay, a proton is converted into a neutron with the addition of energy, and a positron and an electron neutrino is emitted. More fundamentally, an up quark is converted into a down quark, causing the emission of the electron and electron antineutrino. If the beta+ decay also involves K capture, which is the capture of a K shell electron into the nucleus, then there will be subsequent realignment of the electron shells and emission of photons of various energies (x-ray) as the electrons come back to ground state.
How many neutrons in potassium 41?
the answer is 21. because you do 40-19

What is the radioactive emission with the greatest penetrating power?
The three types of natural radioactivity are alpha, beta and gamma radiation. Gamma rays are the most energetic, and the hardest to shield against as they do not readily interact with shielding material. Alpha and beta radiation are actually particles. The beta particle is an electron that has been released. Because of its mass, it more readily reacts with shielding material, and so cannot penetrate as far. Alpha particles are the largest and consist of two neutrons and two protons. Shielding is most effective against alpha particles. Your outer layer of dead skin or a T-shirt is generally enough to protect against alpha particles. However, this effectiveness of shielding does not mean that gamma is always the most harmful and alpha the least. The high effectiveness of shielding on alpha particles is due to the fact that they most readily react with the shield (i.e. damage it). This means that if the alpha particle is able to come in contact with living tissue (like the ingestion of radioactive liquids) it will do far more damage than a beta particle or gamma ray.
How many radiations are emitted by uranium?
Uranium-238 emits alpha radiation; its half-life is 4,468×109 year.
Particles of radioactive emissions?
Alpha particle - (helium nucleus) with a positive charge Beta particle (high speed electron) with a negative charge Gamma ray (electromagnetic radiation) with no charge Radio active decay occurs because the nucleus is unstable. It depends on the particular atom which decay path it will take. A stable atom normally has a few more neutrons than protons. If there are one or two extra neutrons, but not enough to make it stable, getting rid of two of each will slightly increase the proportion of neutrons making it just a little more stable. In this case ALPHA radiation is the result. This consists of helium nuclei with two protons and two neutrons. If there are too many neutrons, one can turn into a proton. When this happens an electron must come into existence by being ejected from the neutron. This is called BETA radiation. If there are too many protons, one of them can eject a positron (positively charged electron) and turn into a neutron. The positron will then very quickly unite with an electron. When this happens they annihilate each other and become very high energy photon (light particle/wave) called a GAMMA ray. This happens mostly in nuclear reactors or in bombs. An example of beta (electron emission) radiation is when Radium 225 loses an electron and turns into Actinium 225 (half life 14.8 days). An example of alpha radiation is when the resulting Actinium loses a helium nuclei or alpha particle to become Francium 221. (half life 10 days) During these processes, other particle called neutrinos are also formed just as they are in the sun. For more about particles check related links below
Are protons neutrons and electrons atoms?
No they are not in the same way that arms and legs are not people.Protons, neutrons and electrons can come together in some specific numbers form atoms (or molecules). You can also have electrons by themselves. Normally you will not find isolated neutrons and protons. Alpha particles are 2 protons+2 neutrons which are found in radioactive decay.

What is the difference of alpha beta and gamma radiation?
These are types of both particulate and electromagnetic radiation, and alpha and beta are the former while gamma is the latter. Let's look at each one in brief. An alpha particle is a pair of protons and a pair of neutrons all hooked together. It's a helium-4 nucleus, and it's particulate radiation. A gamma ray is electromagnetic radiation (an electromagnetic ray) of very high frequency and energy (which also means very short wavelength). A beta particle is one of two types of particles, either a beta plus particle or a beta minus particle. The beta minus particle is an electron, and a beta plus particle is a positron, or anti-electron (antimatter). Beta radiation is particulate radiation. What is key to understanding these guys is how they are formed. Use the links below to the three questions that specifically speak to the characteristics of each of these types of radiation. These questions are already posted and answered here; no need for repetition.
Where does alpha come from?
Alpha is the first letter of the Greek alphabet.
Why do alpha and beta rays deflect in an opposite direction?
Alpha particles deflect backwards due to repulsive electrostatic force between the particles and nucleus. They are all charged positively (like charges repel), hence the repulsive electrostatic force
Atom smallest particle in the universe?
The Atomic nucleus is made up from Protons, Neutrons and to a very small part of Electrons. Protons & Neutrons in term are made up of Quarks. Quarks come in six different flavours and are as follows: up, down, charm, strange, top and bottom.
What year did Minecraft Alpha come out?
