WebMay 5, 2024 · The three parts of the atom are protons (positively charged), neutrons (neutral charge), and electrons (negatively charged). Protons and neutrons form the atomic nucleus. Electrons are attracted to the protons … WebSep 23, 2024 · Example 3.7. 1: Nitrogen Atoms Nitrogen has 7 electrons. Write the electron configuration for nitrogen. Solution: Take a close look at Figure 9.6.5, and use it to figure out how many electrons go into each sublevel, and also the order in which the different sublevels get filled. 1. Begin by filling up the 1 s sublevel. This gives 1s2.
