Question
Lithium has an electronic structure of 2,1.For an atom of lithium to become stable, which one of the following will it need to do?
Solution
For an atom of lithium to become stable, it will need to lose one electron. This is because lithium is in Group 1 of the periodic table, which means it has one electron in its outermost shell. Atoms are most stable when their outermost shell is full. For lithium, the closest full shell is the first shell, which can hold up to two electrons. Therefore, by losing its one outermost electron, lithium can achieve a stable electronic structure with a full outer shell.
