Lithium, the chemical element with the symbol Li and atomic number 3, consist of several components. To determine the components that make up lithium, we can refer to the periodic table, which provides valuable information about the elements.

1. Atomic Number: The atomic number of lithium is 3, indicating it has three protons in its nucleus, defining its identity as lithium.

2. Protons: Protons are fundamental particles found in the nucleus of an atom. Since lithium has an atomic number of 3, it possesses three protons.

3. Electrons: In a neutral atom, the number of electrons is equal to the number of protons. Therefore, lithium, with three protons, also has three electrons.

4. Neutrons: Neutrons are uncharged particles found in the nucleus of an atom. The number of neutrons in an element's nucleus can vary, forming different isotopes of the element. For lithium, the most common isotope is lithium-7, which has 4 neutrons. However, lithium can also have isotopes with 3 or 5 neutrons.

In summary, the components that make up lithium are three protons, three electrons, and typically four neutrons (in the most common isotope, lithium-7). The combination of these components defines the chemical properties and behavior of lithium.
