Identify the element in question, which is lithium. The chemical symbol for lithium is Li.
Refer to the periodic table to find lithium. The periodic table provides essential information about each element, including its atomic number.
Understand that the atomic number of an element represents the number of protons in the nucleus of an atom of that element.
Locate lithium on the periodic table. Lithium has an atomic number of 3.
Conclude that a lithium atom contains 3 protons, as the atomic number directly indicates the number of protons.
