Rubidium is a Block S, Group 1, Period 5 element. The electronic configuration is [Kr] 5s¹. In its elemental form rubidium 's CAS number is 7440-17-7. The rubidium atom has a radius of 247.5.pm and it's Van der Waals radius is 200.pm. Rubidium has various applications in medicine and in photoelectronics. Rubidium is available as metal and compounds with purities from 99% to 99.999% (ACS grade to ultra-high purity); metals in the form of foil, sputtering target, and rod, and compounds as submicron and nanopowder. It is used in photo and detection cells production. Rubidium glass compositions have the highest room temperature conductivity. It has been used as a "getter" in vacuum tubes. Rubidium was first discovered by Robert Wilhem Bunsen and Gustav Robert Kirchhoff in 1861.

Titanium is a Block D, Group 4, Period 4 element. The electronic configuration is [Ar] 3d² 4s². In its elemental form titanium's CAS number is 7440-32-6. The titanium atom has a radius of 144.8.pm and it's Van der Waals radius is 200.pm. In its metallic form it is not only very strong and light weight, but also highly resistant to corrosion. Thus it can be found in numerous aerospace and military applications. In its oxide form it used in low grades to produce a white pigment. Titanium is the bases for numerous commercially essential compound groups, such as titanium titanates in electronic and di-electric formulations and in crystal growth for ruby and sapphire lasers. Titanium information, including Technical Data, Safety Data and its high purity properties, research, applications and other useful facts are discussed here. Scientific facts such as the atomic structure, ionization energy , abundance on Earth, conductivity and thermal properties are included.
