About this document
Understanding the Periodic Table by tasnim is a document available to read on EtoBox.
An element is a pure substance made of only one type of atom. Elements are represented by symbols derived from their names, such as Na for sodium. The periodic table arranges the elements and displays their properties, with metals separated from non-metals by a zigzag line. It organizes elements by their atomic structure into rows called periods based on the number of electron shells, and columns called groups based on their number of outer shell electrons.
