cesium
they belong to group I and almost have same atomic radii and they have same tendency to lose electron.
This statement is not true.
No. Cesium is a group one metal, also known as an alkali metal along with Lithium, Sodium, Potassium , Rubidium, and Francium.
the answer to this question is copper and silver :')
Potassium. It has two extra shells than lithium.
Cesium
Potassium has a higher ionization energy than cesium.
Lithium: No Sodium: Yes Potassium: Yes Rubidium: No cesium: No
cesium
sodium, hydrogen, rabidium, potassium,cesium, and francium
they belong to group I and almost have same atomic radii and they have same tendency to lose electron.
All have the same number of valence electron (i.e., one).
There are more then two: potassium and lithium are the nearest, and there are rubidium, cesium, and francium as well in this group.
Lithium, Sodium, Potassium, Rubidium, Cesium, Francium.
Cesium and Potassium are both elements that explode in Water!
