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.
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 is 7, the number of protons in each nitrogen atom. Its mass number of 14 is the total number of protons and neutrons. The periodic table lists nitrogen’s atomic mass as about 14.01 amu, a weighted average of its isotopes and close to the combined mass of the protons and neutrons in N-14.
