Two protons and a deuteron fuse to form a nucleus with a positron. The product
nucleus may be
a) neutron b) proton c) neutrino d) alpha particle
Answers
Answer:
Answer:
The answer is d) alpha particle
Explanation:
Alpha particles, also called alpha rays or alpha radiation, include protons and neutrons bound together right into a particle identical to a helium-four nucleus. they are commonly produced within the technique of alpha decay, however may also be produced in other approaches.
it is named after the first letter within the Greek alphabet, α. The image for the alpha particle is α or α2+. because they're identical to helium nuclei, they may be also once in a while written as He2+
or four
2He2+
indicating a helium ion with a +2 rate (lacking its electrons). once the ion gains electrons from its surroundings, the alpha particle turns into a everyday (electrically impartial) helium atom 4
2He.
Alpha debris have a net spin of zero. because of the mechanism of their production in fashionable alpha radioactive decay, alpha particles normally have a kinetic power of approximately 5 MeV, and a speed within the place of 4% of the velocity of light.
they are a notably ionizing shape of particle radiation, and (whilst attributable to radioactive alpha decay) typically have low penetration depth (stopped by using a few centimeters of air, or by means of the pores and skin).
but, so-known as long variety alpha particles from ternary fission are three times as energetic, and penetrate 3 instances as a long way. The helium nuclei that form 10–12% of cosmic rays are also usually of tons higher electricity than those produced by way of nuclear decay methods, and thus can be surprisingly penetrating and capable of traverse the human frame and additionally many meters of dense solid defensive, depending on their strength.
To a lesser quantity, this is also genuine of very high-energy helium nuclei produced by way of particle accelerators.
