Responses
It is an Alkali metal

The correct response is **All of the above**. Each of the factors contributes to Francium's low electronegativity:
1. **It is an alkali metal** - Alkali metals generally have low electronegativities.
2. **It has only 1 valence electron** - This makes it easy to lose that electron rather than attract others.
3. **It is in the 7s energy level, making it large with electrons, therefore less attracted to its nucleus** - The larger atomic size means that the valence electron is further from the nucleus and less strongly attracted, leading to lower electronegativity.
Thus, all these factors combined result in Francium having a low electronegativity.
