Question
Chapter 8, Problem 1QQ
To determine
The group of particles having greatest mass among the given options.
Expert Solution & Answer
Answer to Problem 1QQ
Among the given options, the group of particles that has the greatest mass is (c) four individual protons.
Explanation of Solution
Introduction:
The mass of particles is generally expressed in
A helium nuclide has a mass 4.002602 u
The mass of a proton in atomic mass units is 1.007276 u. Therefore, the mass of 4 protons is
The mass of an electron is 0.00054858 u. The mass of 4 electrons is
Conclusion:
Thus, it can be seen that the mass of 4 protons (4.0291 u) is the greatest among the three groups given. Hence the correct option is (c).

For this question, CHOOSE THE CORRECT ANSWER, then explain your reasoning in the RATIONALE section below: Alpha,
Beta-plus, Beta-minus and Gamma decay are all different forms of radio-Active decay. A certain radio-isotope emits ONE
alpha particle, and its products then emit TWO beta-minus particles in succession. The atomic number of the final resulting
nucleus will now change (as compared to your starting nucleus) by
O A. zero
O B. minus 1
OC. minus 2
O D. minus 3
For this question, CHOOSE THE CORRECT ANSWER, then explain your reasoning in the RATIONALE section below: Alpha, Beta-plus, Beta-minus and Gamma decay are all different forms of radio-Active decay. Suppose that a certain radioIsotope could emit TWO alpha particles, and its product (daughter nucleus) could then emit ONE beta-minus particle. The atomic number of the resulting element would be changed by
