Verified step by step guidance1
Understand that the atomic number of an element is defined as the number of protons in the nucleus of an atom of that element.
Recognize that each element on the periodic table is uniquely identified by its atomic number.
Identify the given information: the element in question has three protons.
Conclude that the atomic number of the element is equal to the number of protons, which is 3.
Verify by checking the periodic table: the element with atomic number 3 is Lithium (Li).
