Nitrogen-14 and nitrogen-15 are isotopes,and nitrogen-15 is used to determine protein structure.Based on this information,one can conclude that nitrogen-15 has _______ nitrogen-14.

Question

Quizplus · Accepted Answer

Isotopes have the same number of protons (hence the same atomic number) and different numbers of neutrons. Therefore, nitrogen-15 must have more neutrons than nitrogen-14 to be considered an isotope of nitrogen. The use of nitrogen-15 to determine protein structure is based on its ability to be incorporated into the protein during synthesis, allowing for tracing and analysis.
