The mass of \[\alpha \] particle is
A. 4Mp
B. 4Mu
C. \[2M_c+2M_n\]
D. \[2M_c+2M_p\]

Hint: Alpha positively charged particle ore Fast moving packet – contain or consist of two protons and two Newton. These particles are produced by the alpha decay of a radioactive nucleus.

Complete step by step answer:
Alpha particles also known as alpha rays or alpha radiation. They are produced by the alpha decay of radioactive nucleus, but may also be produced in other ways.
In this process the radioactive nucleus which is very unstable emits an alpha particle.
Alpha particles carry high electrical charge but have too low velocity due to its large mass.
Alpha Decay produced alpha particles. Its mass is due to two protons and two Neutrons bonding.
Alpha particle is very similar to the Helium nucleus.
Alpha particles consist of two protons and two neutrons bound together into a particle identical to a helium-4 nucleus.
Alpha particle is named after the first letter in the Greek alphabet (α). The symbol of the alpha particle is α or α2+ because they are identical to helium nuclei.
If the ion gains electrons from its environment, the alpha particle becomes a normal (electrically neutral) helium atom.
Researchers are currently trying to use the damaging nature of alpha emitting radionuclides inside the body by directing small amounts towards a tumor.
The alphas damage the tumor and stop it growth, while their small penetration depth prevents radiation damage of the surrounding healthy tissue
\[\alpha =H{{e}^{2+}}\]
\[\alpha =2M_p+2M_n\]
Where Mp = mass of proton
Mn = mass of Neuron
Therefore, the correct choice is (C) \[2M_p+2M_n\]

Note:
Basically Alpha particles are the particles that exert from an unstable atomic nucleus that produce by alpha decay.
Alpha Radiations are used to treat various forms of cancer.
