Write a brief passage describing a neutral atom of nitrogen-14 (N-14). Describe the number of protons, neutrons, and electrons in the atom, where each type of particle is located, and how the terms atomic number, mass number, and atomic mass are related to the particles. Use the periodic table to help you.

Answer:

A neutral nitrogen-14 atom has 7 protons and 7 neutrons in its nucleus, and 7 electrons in orbitals around the nucleus. Nitrogen’s atomic number, 7, is its number of protons. Its mass number, 14, is the sum of its protons and neutrons. The mass of nitrogen-14 is approximately the combined mass of those protons and neutrons; the atomic mass on the periodic table is a weighted average of nitrogen’s naturally occurring isotopes.
