Question

Consider the following statements.

(I) Among species isoelectronic with $A r$ , the one with the greater positive charge has more protons.

(II) The specific charge of an α-particle is twice that of a proton.

(III) An α-particle and a deuteron have nearly the same specific charge.

Which of the statements is/are correct?

TestHub · Accepted Answer

(I) Same number of electrons, so protons = electrons + charge. True.

(II) α: $2 e /4 = e /2$ per u, proton: e/1, so the α-particle's is half. False.

(III) Deuteron: e/2 per u, and α: $2 e /4 = e /2$ per u. True.

Answer: (C).
