Question

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.

Explanation:

A neutral nitrogen - 14 atom has 7 protons (atomic number \(Z = 7\)), 7 neutrons (\(n=14 - 7=7\)), and 7 electrons. Protons and neutrons are located in the nucleus. Electrons are located in the electron - cloud surrounding the nucleus. The atomic number (\(Z\)) is equal to the number of protons. The mass number (\(A\)) is the sum of the number of protons and neutrons (\(A=Z + n\)). The atomic mass is approximately equal to the mass number (for a single isotope like \(N - 14\)), but for elements with multiple isotopes, the atomic mass is a weighted average of the masses of its isotopes.

Answer:

A neutral nitrogen - 14 atom has 7 protons (in the nucleus), 7 neutrons (in the nucleus), and 7 electrons (in the electron - cloud around the nucleus). The atomic number (\(Z = 7\)) is the number of protons. The mass number (\(A = 14\)) is \(Z + n\) (where \(n = 7\)). The atomic mass of \(N - 14\) is approximately equal to its mass number.
