Francium (Fr) down a group, the radius increases.
H Li Na K Rb Cs Fr
We know the chemical symbols of caesium and francium are Cs and Fr, respectively.
The alkali metals are: Li, Na, K, Rb, Cs, Fr.
In reaction with water and oxygen Fr is more reactive than Cs
group 1 is Li, Na, K, Rb, Cs and Fr.
Li Na K Rb Cs Fr (hope this is help)

Group 1 Li, Na, K, Rb, Cs, Fr
The alkali metals family contain Li, Na, K, Rb, Cs and Fr.
Li, Na, K, Rb, Cs, Fr, Be, Mg, Ca, Sr, Ba, Ra.
Alkali metals: Li, Na, K, Rb, Cs, Fr.
