3. analyze: an isotope is an alternative form of an element. each isotope of an element has the same number of protons, but a different number of neutrons. the isotope is represented by the atomic symbol and mass number, such as he - 4. some isotopes are stable, while others are radioactive, which means the atoms decay over time and emit radiation.\na. what are the stable isotopes of carbon?\nb. what are the stable isotopes of nitrogen?\nc. list two radioactive isotopes of oxygen?

Answer

Brief Explanations:

A. Carbon has two stable isotopes, carbon - 12 and carbon - 13. They are stable because their nuclear configurations do not undergo spontaneous radioactive decay. B. Nitrogen has two stable isotopes, nitrogen - 14 and nitrogen - 15. These isotopes have a balanced number of protons and neutrons in their nuclei, making them stable. C. Oxygen has several radioactive isotopes, two of which are oxygen - 13 and oxygen - 15. These isotopes are unstable and decay over time, emitting radiation.

Answer:

A. Carbon - 12, Carbon - 13 B. Nitrogen - 14, Nitrogen - 15 C. Oxygen - 13, Oxygen - 15
