They are all in the same column in the periodic table which means that they only have one electron and react easily with other elements.
Rubidium (Rb) can react with many things such as hydrogen because rubidium has one spare electron 2, 8, 18, 8, 1 and hydrogen has only one outer electron so hydrogen in water will reactvigorously with rubidium as hydrogen is desperate to gain one electron and rubidium is desperate to lose one electron and when these bond they form an ion.
Sodium is Na, potassium is K, rubidium is Rb.
Chlorine ,Bromine and Iodine have same chemical properties as Fluorine.
Sodium has a melting point of 97.72 oC and rubidium has a melting point of 39.48 oC.
In addition to hydrogen, all elements in Group I of the periodic table have one valence electron. They are lithium, sodium, potassium, rubidium, cesium, and francium. The farther you move right on the periodic table the more valence electrons. For example, elements in Group VII have 8 valence electrons except helium.
Hydrogen, Lithium, Sodium, Potassium, Rubidium, Cesium, and Francium.
One of the ways the Periodic Table is organized is by rows. After Hydrogen, the next four elements is: Lithium, Sodium, Potassium and Rubidium. These are also in the same Group as Hydrogen therefor they are the closest to having similar properties to Hydrogen. I'm studying the Periodic Table in class. (Eighth grade Science.)
Rubidium (Rb) can react with many things such as hydrogen because rubidium has one spare electron 2, 8, 18, 8, 1 and hydrogen has only one outer electron so hydrogen in water will reactvigorously with rubidium as hydrogen is desperate to gain one electron and rubidium is desperate to lose one electron and when these bond they form an ion.
Sodium is Na, potassium is K, rubidium is Rb.
these are in alkali metal groupsso the names are hydrogen, lithium, sodium, potassium, rubidium, caesium
Hydrogen, lithium, sodium, potassium, rubidium, cesium, and francium have one valence electron.
Chlorine ,Bromine and Iodine have same chemical properties as Fluorine.
Sodium has a melting point of 97.72 oC and rubidium has a melting point of 39.48 oC.

The farther you move right on the periodic table the more valence electrons. For example, elements in Group VII have 8 valence electrons except helium.
Lithium, Sodium, Potassium, Rubidium, Cesium, and Francium all share the same group, one valence electron, so they will all have similar characteristics.
Seven elements are found in group A or group 1.These are Hydrogen,Lithium,Sodium,Potassium,Rubidium,Caesium and Francium. Except Hydrogen all are metals.
