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!
