Here's the significance of PERIOD and GROUP in the periodic table: Period (Horizontal Rows): The period number indicates the number of electron shells* or energy levels an atom has. For example, elements in Period 3 have electrons occupying three main energy shells. As you move across a period from left to right, the atomic number increases, and the number of valence electrons* generally increases, leading to a gradual change in chemical properties. Group (Vertical Columns): The group number (for main group elements) indicates the number of valence electrons* an atom has. For example, all elements in Group 1 have one valence electron. Elements within the same group share similar chemical properties* because they have the same number of valence electrons, which largely determines how an atom reacts.
