The atomic number is really important for understanding the periodic table! Here’s why:
Identity: The atomic number is like an "ID card" for each element. It tells us exactly what the element is.
Arrangement: Elements are lined up in order of atomic number. This helps us spot patterns among them.
Groups and Periods: The table has vertical columns called groups. These show elements with similar properties. The horizontal rows, or periods, show how many electron shells an element has.
So, the atomic number helps us learn about how elements are related to each other!
