- The Periodic Table Chemistry Goal Three
- Slide 2
- The periodic table is used to identify the basic organization of elements.
- Slide 3
- Every periodic table will have a square for each element with the following: a) atomic number the number of protons in each atom b) atomic mass average mass of the element c) element name d) element symbol
- Slide 4
- The elements on the periodic table are arranged numerically by atomic number.
- Slide 5
- A horizontal row on the periodic table is called a period. Families, aka groups, are vertical columns of elements on the periodic table. Elements in the same family have similar properties. Periods Family
- Slide 6
- There is a zig zag line on the right side of the table. It divides the periodic table into two sections of elements, metals and nonmetals.
- Slide 7
- Metals A major group of elements on the left of the zigzag line. Examples: Sodium (Na), Calcium (Ca), Iron (Fe), and Aluminum (Al) The majority of the elements are metals. Sodium Metal Calcium Metal Iron Ore Aluminum
- Slide 8
- Nonmetals A major group of elements on the right of the zigzag line. Examples of nonmetals: Chlorine (Cl), Oxygen (O), Sulfur (S), and Iodine (I) Chlorine Gas Liquid Oxygen Sulfur Crystals Iodine
- Slide 9
- Chemical symbols show which elements compose a substance. Symbols are written with one, two, or three letters The first letter is always capitalized. The second or third letter is always lowercase. Each element has a different symbol. Oxygen = O Sodium = Na Unununium = Uuu
