Final answer:

The atomic number of Lithium is always 3, reflecting the number of protons in its nucleus.


Explanation:

The atomic number of Lithium is 3, as it has 3 protons in its nucleus consistently across isotopes. For example, Lithium-6 has 3 protons and 3 neutrons with an atomic number of 3 and a mass number of 6. Similarly, Lithium-7 contains 3 protons and 4 neutrons with an atomic number of 3 and a mass number of 7.
