Build atoms just as you did before. Examine the chemical symbol and the three numbers. What does the chemical symbol show?

In chemistry, a chemical symbol can be described as a shorthand method for an element. In such a way, we are at ease. Instead of writing the name of any particular element, we can simply represent it with a symbol. For example, they symbol for the element iron is Fe. The symbol for the element hydrogen is H. The symbol for the element helium is He. The symbol for the element nitrogen is N.

It's a short form, or abbreviation, of the element name.
