The largest neutral atom currently known is **francium (Fr)**, which has the atomic number 87. It is an alkali metal and is considered the least stable and rarest of the first 101 elements on the periodic table. Francium has a very short half-life and is highly radioactive, but in terms of atomic radius, it is the largest among the neutral atoms due to its position in the periodic table and the increasing number of electron shells as you move down the group.
However, if we consider more stable larger atoms, **cesium (Cs)** (atomic number 55) is also known for having a significant atomic radius, but it is not larger than francium in terms of atomic size.
In summary, francium is generally regarded as the largest neutral atom when considering atomic radius.
