Concept explainers
The correct statement.
Explanation of Solution
Introduction:
The radioactive particles alpha, beta and gamma rays are formed due to radioactive decay. The alpha particles consists two protons and two neutrons. The beta particle consists one electron. The gamma rays are massless energy.
The nucleus of helium atom consists two proton and two neutrons in the nucleus. The alpha particles also consists two protons and two neutrons, so the alpha particle is same as the helium atom. The alpha particle is the byproduct of radioactive decay. So, Helium atom also. So, the first statement is correct.
Conclusion:
Thus, the first statement is correct.
