Verified step by step guidance1
Recall that lithium (Li) is an alkali metal located in Group 1 of the periodic table.
Elements in Group 1 typically lose one electron to achieve a stable electron configuration similar to the nearest noble gas.
When lithium loses one electron, it forms a cation with a charge of +1, because it now has one more proton than electrons.
Therefore, the typical ionic charge of lithium when it forms an ion is +1.
The other options (+2, -1, 0) do not correspond to the common ionic state of lithium in chemical compounds.
