What is the PERIODIC TABLE? The periodic table shows all known elements in the universe. It organizes the elements by chemical properties. Success Criteria: Can I recognize that all matter consists of atoms? (SPI0807.9.1) Can I use the Periodic Table to determine the properties of an element? (SPI0807.9.9)

Compare and Contrast: Elements The elements alone or in combinations, make up our bodies, our world, our sun, and in fact the entire universe! Discuss with your elbow partner some different elements that make up humans and other organisms. Success Criteria: Can I recognize that all matter consists of atoms? (SPI0807.9.1) Can I use the Periodic Table to determine the properties of an element? (SPI0807.9.9)

Periodic Table and Classes of Elements Elements on the periodic table can be grouped into families based on their chemical properties. Each family has a specific name to differentiate it from the other families in the periodic table. Elements are classified as metals, nonmetals, and metalloids, by their properties. Metals are found to the left of the zigzag line. Atoms of most metals have few electrons in their outer energy shell. Success Criteria: Can I recognize that all matter consists of atoms? (SPI0807.9.1) Can I use the Periodic Table to determine the properties of an element? (SPI0807.9.9)

Periodic Table and Classes of Elements Nonmetals are found to the right of the zigzag line. Atoms of most nonmetals have an almost complete set of electrons in their outer energy shell. Metalloids are the elements that border the zigzag line. Atoms of metalloids have about half of a complete set of electrons in their outer energy shell. These are also called semiconductors.
