Smallest to largest is going down the group 1. I.e. Li is smallest<Rb<Cs
Rb is the largest, Li the smallest in the row above. Group 1 of the periodic table: Fr > Cs > Rb > K > Na > Li > H
Rb
Li+ , Na+ , K+ , Rb+ , Cs+ , Fr+
The alkali metals are: Li, Na, K, Rb, Cs, Fr.
H Li Na K Rb Cs Fr
H Li Na K Rb Cs
group 1 is Li, Na, K, Rb, Cs and Fr.
Group 1 Li, Na, K, Rb, Cs, Fr
Li Na K Rb Cs Fr (hope this is help)
Li+,Na+,K+,Rb+,Cs+,Fr+
The alkali metals family contain Li, Na, K, Rb, Cs and Fr.
