Consider the following statements: I - The penetration power of alpha radiation (α) is greater than that of gamma radiation (γ). II - The loss of a beta particle (β) by an atom results in the formation of an atom with a higher atomic number. III - The emission of gamma radiation from the nucleus of an atom does not alter the atomic number or the mass number of this atom. IV - The decay of ²²⁶Ra to ²¹⁴Bi involves the consecutive emission of three alpha particles (α) and two betas (β). Of the statements presented, only the following are correct:

Chemistry

Statement I is incorrect because gamma radiation (γ) has greater penetration power than alpha radiation (α). Statement II is correct, as when an atom emits a beta particle (β), its atomic number increases by one unit. Statement III is also correct, as the emission of gamma radiation does not alter the atomic number or mass number of the atom. Statement IV is incorrect, as the decay of ²²⁶Ra to ²¹⁴Bi involves the emission of four alpha particles (α) and two betas (β). Therefore, the correct statements are II and III.
