WebPeriodic trends are repeating patterns found in the periodic table as you move across a period or down a group. In the periodic table, rows are known as periods and columns are known as groups. Elements in the same period have the same number of electron shells, but differ in their number of outer shell electrons. WebPeriodic Trends. In the SparkNote on the Periodic table we discussed a number of simple periodic trends. In this section we will discuss a number of more complex trends, the understanding of which relies on knowledge of atomic structure. Before getting into these trends, we should engage a quick review and establish some terminology. hubungan pancasila dengan negara
