Answer for screen readers
The periodic table is a tabular arrangement of all known chemical elements, organized by atomic number, which shows recurring chemical properties.
More Information
The periodic table is fundamental in understanding the chemical behavior of elements. It not only sorts elements into metals, nonmetals, and metalloids, but also indicates trends such as electronegativity, atomic size, and ionization energy.
Tips
A common mistake is confusing the order of elements by atomic mass instead of atomic number. Remember, Mendeleev's early tables used atomic mass, but the modern table uses atomic number.
