Atoms themselves are composed of protons, neutrons, and electrons. Each element has its own atomic number, which is equal to the number of protons in its nucleus. Isotopes of an element contain different numbers of neutrons. Elements are represented by an atomic symbol. The periodic table is a chart that organizes all the elements.

All elements exist as a collection of isotopes, and the mass of an element that we use in chemistry, the atomic mass, is the average of the masses of these isotopes.

It notes that electronegativity increases across periods and decreases down groups, highlighting fluorine as the most electronegative element. Metals generally have low electronegativities due to their tendency to lose electrons, while nonmetals gain electrons, leading to higher values.
