How do you determine the atomic number
WebJun 2, 2024 · Find the Number of Electrons. For a neutral atom, the number of electrons is the same as the number of protons. Often, the number of protons and electrons is not the … WebThe periodic table describes the atomic structure of all known elements. For instance, by looking at the periodic table, you can find out the atomic mass and the number of electrons the element has. Each element has its own separate set of such data. No two elements are the same. This is perhaps the most useful feature of the Periodic Table.
