Question

Pick out the correct statements:

• A. Nuclei with certain even numbers of protons and of neutrons are the most stable
• B. ${}_6^{14}\text{C}$ is stable isotope of carbon
• C. Nuclides that lie below the belt of stability are proton rich
• D. New elements and isotopes of known elements are made by nucleo synthesis

Answer 1

Answer: (A), (C), (D)

The correct options are
A Nuclei with certain even numbers of protons and of neutrons are the most stable
C Nuclides that lie below the belt of stability are proton rich
D New elements and isotopes of known elements are made by nucleo synthesis

Nucleosynthesis is the process of creating new atomic nuclei from pre-existing nucleons (protons and neutrons) so new elements and isotopes of known elements are made by nucleo synthesis.

${}_6^{14}\text{C}$ is an unstable isotope of carbon and nuclides that lie below the belt of stability are proton-rich.

Nuclei with certain even numbers of protons and of neutrons are the most stable. Example: ${}_6^{12}C,{}_8^{16}O,$ etc.
