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 atom of nitrogen-14 (N-14) contains 7 protons and 7 neutrons located within its central nucleus. Since the atom is neutral, it also contains 7 electrons located in orbitals surrounding the nucleus. Nitrogen's atomic number is 7, which matches its number of protons. The mass number of 14 is the sum of the protons and neutrons (7 + 7 = 14). The atomic mass is approximately 14 amu, as it is determined by the total mass of the protons and neutrons.
An atom of sodium-23 (Na-23) has a net charge of +1. Identify the number of protons, neutrons, and electrons in the atom. Then, explain how you determined the number of each type of particle. Use the periodic table to help you.
It contains 11 protons in the nucleus. It contains 12 neutrons in the nucleus. It contains 10 electrons surrounding the nucleus. The number of electrons are calculated from net charge and charge of proton (+1) and electron (–1). 12 neutrons are calculated from atomic number: 11 and mass number: 23.
