Understanding the Atomic Number of an Element

The atomic number of an element represents the number of protons in the nucleus of its atom. This fundamental property determines the identity of the element and its place on the periodic table. For example, the atomic number of hydrogen is 1, indicating it has 1 proton, while the atomic number of oxygen is 8, signifying it has 8 protons. Understanding atomic numbers helps students grasp the organization and properties of elements, laying a strong foundation for advanced chemistry concepts.
