Which particle is most massive in radioactivity?
You think probable to alpha particles.
Which of these masses is the largest alpha particle antineutrino gamma radiation beta particle?
Alpha Particle
Is alpha particle is heavy particle?
An alpha particle is a helium-4 nucleus. It has a mass of about 4 atomic mass units.
Why the alpha particles could not smash the nucleus apart?
The alpha particle is positively charged (as is the nucleus) and is heavy compared with the neutron that is neutral and lighter than the alpha particle.Another viewpoint:It depends what experiment the question is about. For example, over a hundred years ago, Rutherford bombarded gold foil with alpha particles and some "bounced off" what we now call the nucleus of the atoms. However, about ten years later he did experiments in which alpha particles did indeed "split" atomic nuclei. So, sometimes alpha particles can certainly smash a nucleus apart.
What is made up of 2 protons and 2 neutrons?
In terms of radioactivity it is an alpha particle.
Who said atoms were made up of subatomic particles?
Rutherford proved it it from his alpha-particle scattering experiment.
What is a subatomic particle with two neutrons that is emitted during some types of radioactive decay called?
This would be the alpha particle. An alpha particle has two neutrons and two protons, and it's actually a helium-4 nucleus. That's why we write this particle like this: 42He or He+2 Use the links below for more information.
What causes some of the alpha particles to bounce straight back from the gold foil?
Alpha particles are composed of two neutrons and two protons, so they have a positive charge. When the alpha particles bounced straight back from the gold foil, this indicated that they had hit a particle of like charge, in other words a positively charged particle in the gold foil, which repelled the alpha particle.
Is alpha radiation uncharged?
No, alpha particles are not uncharged. An alpha particle is actually a helium-4 nucleus, and that means it's composed of 2 protons and 2 neutrons. It will have an overall charge of +2, and we often write the alpha particle as He++ or He2+. The related question on what an alpha particle is can be found below. Check it out.
Are alpha rays neutrons?
Alpha particles are helium nuclei -- each particle is composed of two protons and two neutrons. A stream of alpha particles may be called a ray, although as it is not electromagnetic radiation that is probably inaccurate.
What subatomic particle has the longest wave length a neutron proton electron or alpha particle?
energy
Which particle is composed of 2 neutrons and 2 protons?
An alpha particle.
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 is the alpha particles?
The symbol of the alpha particle is the small Greek letter alpha, α
Which naturally occurring radioactive particle is the largest?
Alpha particles are the same size as a helium nucleus and are made up of 2 protons and two neutrons. They have no electrons so an alpha particle has a +2 charge
How much force can an alpha particle exert?
This depends on the velocity, or temperature, of the alpha particle. The faster the particle goes, the higher its temperature, and the more energetic it is. When we are dealing with atoms and subatomic particles, temperature and velocity are pretty much measurements of the same thing. Most alpha particles emitted from large radioactive atoms have energies in the range of 3 to 7 MeV (million electron volts). Alpha particles from the decay of the heavier, man-made atoms can be more energetic yet. 5 MeV would mean that the particle is going about 15,000 km/s, or about 5% of the speed of light. At that speed, the alpha particle can be absorbed by a piece of thin paper. They are not horribly dangerous, if the particles are outside you. But if they are emitted from something inside you, they can be very destructive because they can alter living cells. It should be noted that an alpha particle is essentially the same thing as a Helium-4 nucleus. The difference is that the alpha particle came from nuclear decay, and is moving.
What gives off alpha particles?
Alpha particles are a type of particle of radiation that is emmited by certain radioactive materials. The materials that give off Alpha particles are called ''Alpha emitters.''
