The single outer electron is further away from the nucleus and thus is less tightly bound and thus it is energetically easier to remove that electron
Rubidium (Rb) shares more similar properties with cesium (Cs) than with strontium (Sr). Both Rb and Cs are alkali metals, which means they have similar chemical properties, including high reactivity and the tendency to form +1 cations. In contrast, strontium is an alkaline earth metal, exhibiting different reactivity patterns and a +2 oxidation state. Thus, Rb is more closely related to Cs in terms of chemical behavior and properties.
Yes, rubidium (Rb) is more reactive than lithium (Li), potassium (K), sodium (Na), and cesium (Cs). In the alkali metal group, reactivity increases as you move down the periodic table due to the increasing atomic size and the decreasing ionization energy, which makes it easier for the atoms to lose their outermost electron. Thus, Rb, being below K and Na, is more reactive than all of them. However, cesium (Cs) is even more reactive than rubidium.
Rb
These six elements are Li, Na, K, Rb, Cs and Fr.
The alkali metal cations are lithium (Li+), sodium (Na+), potassium (K+), rubidium (Rb+), cesium (Cs+), and francium (Fr+). These cations are formed when alkali metals lose their outermost electron to achieve a stable electron configuration.

Smallest to largest is going down the group 1. I.e. Li is smallest<Rb<Cs
Cesium (Cs) shows the least active chemical behavior among these elements. It is located at the bottom of Group 1 in the periodic table and has the largest atomic radius, making it the most reactive metal in Group 1. Rb (Rubidium) and Na (Sodium) are more reactive than Cs.
