There are several ways, one is the flame test.
- lithium - deep red with very slightly purplish color
- rubidium - red violet color
A more precise test would be spectrographic to see the actual line patterns instead of just depending on visible color.

Which element between lithium potassium rubidium and cesium has the smallest ionization energy?
T he smallest first ionization energyis for lithium.
What are sodium lithium and rubidium collectively known as?
Lithium, sodium, potassium, rubidium and cesium are collectively known as the alkali metals.
What elementare in the alkali metal family?
The alkali metals family contain: lithium, sodium, potassium, rubidium, caesium, francium.
Example of an alkali metal?
lithium, sodium, potassium, rubidium, cesium and francium
Elements in group one?
Lithium, Sodium, Potassium, Rubidium, Cesium, & Francium
Which element between lithium potassium rubidium and cesium has the smallest ionization energy?
T he smallest first ionization energyis for lithium.
What are sodium lithium and rubidium collectively known as?
Lithium, sodium, potassium, rubidium and cesium are collectively known as the alkali metals.
Least reactive to most reactive elements Lithium potassium Rubidium.?
rubidium
Does a reaction occur between rubidium and lithium chloride?
Yes. As long as rubidium is kept away from air it can. But, this is very difficult. Rubidium + Air = Explosion. Formula would be LiCl + Rb --> RbCl + Li.
Which of the alkaline metals potassium lithium rubidium or sodium has the highest electronegativity?
This metal is rubidium.
What elementare in the alkali metal family?
The alkali metals family contain: lithium, sodium, potassium, rubidium, caesium, francium.
Is a grass shrimp a producer consumer or decomposer?
No it is rubidium and lithium
Is an lithium an metal?
Yes, along with Sodium, Potassium, Rubidium, Cesium and Francium, Lithium is an alkali metal.
How does electron shielding explain why it is easier to remove an electron from rubidium than from lithium?
In rubidium, having a larger atomic radius, the attraction force between the atomic nucleus and and the electron from outermost shell is lower.
What metal produces a crimson flame?
Calcium, rubidium, lithium and strontium have red (or similar) colors in the flame tast.
Name of lithium's family members?
Lithiums in the group Alkali metals
Which element is the most metallic Calcium Lithium Rubidium or Carbon?
Rubidium. Metallic character increases as you move down and to the left on the periodic table.
