The table summarizes the atomic structure details of elements. For example, hydrogen has 1 proton and 1 valence electron, lithium has 3 protons and 1 valence electron, nitrogen has 7 protons and 5 valence electrons, aluminum has 13 protons and 3 valence electrons, and sulfur has 16 protons and 6 valence electrons.
The periodic table provides a systematic arrangement of elements based on their atomic structure. To fill in the missing information in the table, we can use the periodic table as a reference.
