However, one platform that sta...Aug 26, 2020 · The charge of an atom is defined as follows: Atomic charge = number of protons − number of electrons (1.8.1) (1.8.1) Atomic charge = number of protons − number of electrons. As will be discussed in more detail later in this chapter, atoms (and molecules) typically acquire charge by gaining or losing electrons. The tiny superscripts say how many electrons live in each orbital, the letters represent the orbitals that are available, and the big numbers say which energy level the orbitals are found in. Remember that the total number of electrons just equals the total number of protons, and so the superscripts add up to 8, the atomic number of oxygen.
