The alpha particle emitted in alpha decay will leave the nucleus of the atom with considerable kinetic energy. But it will begin slowing down immediately unless it's in a vacuum. This will be due to scattering events with any atoms or molecules it encounters along its path of travel. It will not experience an increase in velocity, so no, it won't speed up. A link to a related question can be found below.
What else can I help you with?
How many nucleons does an alpha particle contain?
An ALPHA particle may be thought of a a helium nucleus. It contains two protons and two neutrons. An alpha particle is a high speed helium nucleus (He^(2+)).
What represents a beta particle?
0/-1 e
What particle is emitted in beta radiation?
In unstable neuclei where there are 'too many' neutrons, a neutron will convert to a proton and an electron - that electron is ejected from the nucleus and is called a beta particle. It is important that we call this electron a beta particle because it is derived by radioactive disintegration in the nucleus and not an 'orbital' electron.
What is a type of radioactive decay that involves emission from the nucleus of a high speed antimatter particle that is a counterpart of the electron?
This is beta decay, specifically beta plus decay. The beta particle that appears is the positron, which is the antimatter particle of the electron. Links can be found below for more information.
Discuss with the use of examples the main differences between alpha and beta decay?
In alpha decay, an alpha particle (a helium nucleus - 2p+ and 2n0) is emitted from the nucleus of an atom. In beta decay, a neutron turns into a proton and an electron, and the electron (beta particle) is emitted from the nucleus of the atom.

A high-speed electron ejected from a nucleus durng radioactive decay is called a?
an alpha particle
Alpha particles ejected from the nucleus travel at the speed of light?
Alpha particles are emitted from the nucleus at high speeds, typically around 5-10% of the speed of light. They move with such energy due to the strong repulsive force between the positively charged alpha particle and the remaining nucleus.
Does an alpha particle and beta particle has the same speed in a magnetic field?
Alpha particles with the same energy as beta particles have much less speed, magnetic field or no.

What is a negative electron emitted from the nucleus of an atom at high speed?

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.

At what speed do alpha particles travel?
Alpha radiation, like any other form of electromagnetic radiation, travels at the speed of light (300 000 000 metres per second)
An alpha particle charge 2.0e is sent at high speed toward a gold nucleus charge 79e What is the electrical force acting on the alpha particle when it is 3.0 10-14 m from the gold nucleus?
Assuming a positive charge on the Alpha particle...F = (Q1*Q2)/(r2)*KF = (158e2)/(3*10-14)2*(8.988*109)F = 40.4951176224... N = 40NEdit....F=ke(q1)(q2)r^2=(8.99x109 N*m2/C2) (158x1.60x10-19C)2 / (2.0X10-14m)2=91N (the m2and C2 cancels out)

What is another name for beta particle?
Another name for a beta particle is an electron. It is a high-energy, high-speed particle that is emitted during the radioactive decay of certain elements.
