To achieve stability, lithium (Li), which has an electronic structure of $1s^2 2s^1$, needs to follow the octet rule, typically aiming for a full outer shell of electrons. Here’s how it can achieve stability:

1. **Lose an Electron**: Lithium can lose its single $2s$ electron. This results in a $Li^{+}$ ion with the electronic structure $1s^2$, thereby filling its outer shell.
2. **Gain Stability**: By losing this electron, lithium achieves a full outer shell similar to the noble gas configuration of helium (He), which is stable.

Thus, the correct answer is that lithium will need to lose its one valence electron to become stable.
