85.4678 is the atomic weight of Rb.
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!
The chemical symbol of rubidium is Rb Rb-- atomic # 37, atomic weight 85.87
The atomic radius of Sr (Strontium) is larger than that of Rb (Rubidium). This is because atomic radius generally increases down a group in the periodic table, and Sr is located below Rb in the same group.
Rubidium is a metal element. Atomic mass of it is 85.
Rubidium has an atomic radius of 248 picometers.
The atomic mass of rubidium (Rb) is approximately 85.4678 atomic mass units.
The species with the smallest atomic radius among K, Mg, Rb, and Ca is Rb (Rubidium). This is because atomic radius tends to decrease across a period from left to right in the periodic table, and Rb is located towards the right side of this group of elements.
If you look at a periodic table and go to group one, and than the element with an atomic number of 37 it is Rb. The atomic number is the number of protons and electrons. Rb is Rubidium.
Atomic weight = Weight of protons + Weight of neutrons
Unified atomic mass unit
Atomic Number = 6. Atomic Weight = 12.011
