Learning Objectives
  • In this skill we will learn to identify the atomic number of different elements from their symbols and names.
  • The atomic number represents the number of protons in an atom an element.
  • In the periodic table, the atomic number is the number in the top left of the element square.
  • The element symbol is a combination of one or two letters that are a shorthand for representing the element and is shown in large text.
Tips
  • If you don't know the location of an element, start looking across the rows systematically until you find it.
  • This process will get a lot of quicker over time as you become familiar with the periodic table!
