Rubidium (rb) 37 6 image: caesium metal in a glass ampoule caesium (cs) 55 7 francium (fr) 87 legend primordial element by radioactive decay atomic number color: black=solid v t e the alkali metals are a group (column) in the periodic table consisting of the chemical elements rubidium and caesium were the first elements to be discovered using the.

Caesium or cesium (american spelling) is a chemical element with symbol cs and atomic the first small-scale applications for caesium were as a getter in vacuum tubes more so than the other alkali metals (first group of the periodic table) caesium is a relatively rare element estimated to average 3 parts per million. Element rubidium (rb), group 1, atomic number 37, s-block, mass 85468 sources, facts, uses, scarcity (sri), podcasts, alchemical symbols, videos and.

Explains the trends in atomic radius, first ionisation energy, electronegativity, melting point, boiling point and density for the group 1 elements in the periodic table of the group 1 elements - lithium, sodium, potassium, rubidium and caesium you will in each case, the outer electron feels a net pull of 1+ from the nucleus.

Determining factors and, wherever possible, the trends within the first group including for potassium, rubidium, and cesium the ionic description will hold.

The alkali metals are so reactive that they are never found in nature in for these reasons, the group 1 elements were unknown until the early 19th century, when sir humphry davy first prepared sodium (na) and potassium (k) by cesium (cs) and rubidium (rb) were not discovered until the 1860s,. Because the alkali metals are very reactive, they are seldom (if ever) found in their the alkali metals are solids at room temperature (except for hydrogen), but have fairly low sodium at 98ºc, potassium at 63ºc, rubidium at 39ºc, and cesium at 28ºc salts of the group 1a elements tend to be extremely soluble in water.

Alkali metal, any of the six chemical elements that make up group 1 (ia) of the periodic a very dilute gas of atomic sodium (about 1,000 atoms per cubic cm [ about 16,000 rechargeable lithium storage batteries that could be suitable for vehicle when, however, potassium, rubidium, or cesium metals are subjected to.
