Niobium is a Block D, Group 5, Period 5 element. The number of electrons in each of Niobium's shells is 2, 8, 18, 12, 1 and its electronic configuration is [Kr] 4d4 5s1. In its elemental form niobium's CAS number is 7440-03-1. The niobium atom has a radius of 142.9.pm and it's Van der Waals radius is 200.pm. Some niobium compounds are considered very toxic. Niobium is the basis for various barium titanate compositions used as dielectric coatings in telecommunications and small advanced electronics, such as cell phones, pagers and laptop computers. Niobium 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. Niobium has medical research applications. It is alloyed to produce arc-welding rods and in corrosion-resistant steel. Niobium was first discovered by Charles Hatchett in 1801. The word Niobium originates from Niobe, daughter of mythical Greek king Tantalus. See Niobium research below.
Titanium is a Block D, Group 4, Period 4 element. The number of electrons in each of Titanium's shells is 2, 8, 10, 2 and its 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. Titanium metal is not considered to be toxic although titanium as metal shavings or powder is considered a fire hazard. 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. Titanium was first discovered by William Gregor in 1791. Titanium was named after the word Titanos which is Greek for Titans. See Titanium research below.

Niobium is a Block D, Group 5, Period 5 element. The number of electrons in each of Niobium's shells is 2, 8, 18, 12, 1 and its electronic configuration is [Kr] 4d4 5s1. In its elemental form niobium's CAS number is 7440-03-1. The niobium atom has a radius of 142.9.pm and it's Van der Waals radius is 200.pm. Some niobium compounds are considered very toxic. Niobium is the basis for various barium titanate compositions used as dielectric coatings in telecommunications 
and small advanced electronics, such as cell phones, pagers and laptop computers. Niobium 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. Niobium has medical research applications. It is alloyed to produce arc-welding rods and in corrosion-resistant steel. Niobium was first discovered by Charles Hatchett in 1801. The word Niobium originates from Niobe, daughter of mythical Greek king Tantalus. See Niobium research below.
Titanium is a Block D, Group 4, Period 4 element. The number of electrons in each of Titanium's shells is 2, 8, 10, 2 and its 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. Titanium metal is not considered to be toxic although titanium as metal shavings or powder is considered a fire hazard. 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. Titanium was first discovered by William Gregor in 1791. Titanium was named after the word Titanos which is Greek for Titans. See Titanium research below.
