How many neutrons does nitrogen-15 have?

Understand the Problem

The question is asking for the number of neutrons in the isotope nitrogen-15. To find this, we subtract the atomic number of nitrogen (which is 7) from the mass number of nitrogen-15 (which is 15). This will give us the number of neutrons.

More Information

Nitrogen-15 is an isotope of nitrogen that has 7 protons, 7 electrons, and 8 neutrons. This isotope is stable and often used in scientific research.

Tips

A common mistake is to confuse the atomic number (number of protons) with the mass number (sum of protons and neutrons). The mass number is not the same as the neutron count.
