Question

question 5 (1 point) saved listen n-15 is an ???? of nitrogen and has ???? neutrons. a) isotope; 15 b) isotope; 8 c) ion; 15 d) ion; 8 e) isotope; 7

Explanation:

1. First, recall the definition of an isotope: Atoms of the same element with different mass numbers (due to different numbers of neutrons) are isotopes. N - 15 has a mass number of 15. The atomic number of nitrogen (number of protons) is 7.
2. To find the number of neutrons, use the formula: Number of neutrons = Mass number - Atomic number. So, neutrons = \(15 - 7=8\).
3. N - 15 is an isotope (not an ion, as an ion involves a charge from gaining/losing electrons, not changing neutrons). So the correct option is B.

Answer:

B) Isotope; 8
