Understand that the atomic number of an element is defined as the number of protons in the nucleus of an atom of that element.
Recall that the atomic number is a unique identifier for each element and determines the element's position in the periodic table.
Given that carbon has 6 protons, identify that the atomic number of carbon is equal to the number of protons.
Recognize that the atomic number is used to distinguish one element from another in the periodic table.
Conclude that since carbon has 6 protons, its atomic number is 6, which corresponds to the element carbon in the periodic table.
