• Students in high school and undergraduate programs, where chemistry and physics are core subjects.

Before approaching the periodic table, it's essential to grasp the basics. The periodic table is arranged in a logical order based on the atomic number (number of protons in the nucleus) and electron configuration. The atomic number is a unique identifier for each element and increases incrementally across the table. The mass number is the sum of protons and neutrons in the nucleus and represents the total mass of the atom.
