The atomic number of rubidium is 37.
Rubidium is a metal element. Atomic mass of it is 85.46.
The atomic number of rubidium (Rb) is 37.The atomic weight of Rb is 85.4678(3) grams per mole.See the Web Links to the left of this answer for a periodic table with more information about this element!
Rubidium has an atomic number of 37, making it an alkali metal. This means that its last shell is an s with only one electron. The full notation is [Kr] 5s1.
The atomic radius depends on the the number of electron shells, total negative charge, positive charge of the nucleus, atomic mass.
If rubidium (Rb) loses 1 electron, it will have a charge of +1 because it is losing a negative electron, resulting in a positive charge.
The atomic number of rubidium is 37.
Francium is radioactive and rubidium not. Also the electron configuration, atomic number, physical properties, hazards etc. are different.

Atomic number is the number of protons in the nucleus of an atom. Therefore, sodium's atomic number is always 11, even if it loses 1 electron. However, when a sodium atom loses 1 electron, it will form an ion with a 1+ charge.
