Li⁺

Explanation:

The atomic number of lithium is 3, which means that it has 3 protons and 3 electrons. The electron configuration is [He] 2s¹ and its Lewis structure is Li·

When lithium loses an electron to form lithium cation, its Lewis structue is Li⁺ and it acquires the electron configuration of Helium: 1s².
