Understanding the Atomic Number of an Atom

The atomic number of an atom represents the number of protons in its nucleus. In simpler terms, it defines the identity of the element. For example, if an atom has 6 protons, its atomic number is 6, making it carbon. This characteristic distinguishes one element from another. Understanding the atomic number is crucial in comprehending the periodic table and chemical reactions. It is a fundamental concept in the study of atoms and chemistry.
