Yes, the periodic table is organized in order of increasing atomic number. The atomic number represents the number of protons in an atom's nucleus and determines the element's identity. In the periodic table, elements are arranged in rows called periods and columns called groups or families. As you move from left to right across a period or from top to bottom within a group, the atomic number increases sequentially, reflecting the increasing number of protons and electrons in the elements. This arrangement allows for a systematic organization of elements with similar properties and facilitates the understanding of trends and patterns in the periodic table.
