Each element is represented by a symbol, which is typically a one- or two-letter abbreviation of its name! 🔠 The elements are arranged in order of increasing atomic number, which is the number of protons in the nucleus of an atom! The periodic table has played a crucial role in the development of modern chemistry, and it continues to be an essential tool for scientists and students of chemistry 🧪👩🏻🔬⚛️
