Answer:

(4) loses an electron

it has 3 protons and electrons, proton no. cannot change, to make lithium an ion, it needs to have an exact number of electrons so that the electronic shell can be 2, 8… something like that. So lithium atom loses an electron in order to for Li+ ion. Making the electrons to have 2 as an electronic shell.
