Question

Given below are the nuclear symbols for three different types of nuclear particles: a proton (H+), a deuteron (2H+), and a helium-3 nucleus (3 He2+). Assuming all three particles have the same energy, arrange them in order from most penetrating to least penetrating.
1. = A 3 He2+
2. = B TH+
3. = C 2H+

    Answer:

    [tex]^1 H^+ < \ \ ^2H^+< \ \ ^3He^{2+}[/tex]

    Explanation:

    Based on the given information, assuming that all three nuclear particles are isoelectronic, the greater the attraction from the nucleus, the greater the penetration. The greater the attraction to the nucleus, however, the less shielding there would be, resulting in a high effective nuclear charge.

    Hence, in increasing of most penetrating to least penetrating, the arrangement is as follows.

    [tex]^1 H^+ < \ \ ^2H^+< \ \ ^3He^{2+}[/tex]

    least                      most

    penetrating           penetrating
