Positively charged protons (in pink) and neutral neutrons (in black) present at the centre. 2018-01-12 · The atomic numbers go in order on the table. While other numbers may be decimal values, the atomic number is always a simple positive whole number. For example, if you are told the element name is aluminum, you can find the name or symbol Al to determine the atomic number is 13.
