Chances are that somewhere in there you'll turn up a mobile phone. A mixture of powdered tantalum and tantalum oxide is used in mobile phone capacitors, components that store electrical charge and control the flow of current. The new metal's refusal to react when immersed in acid reminded Ekeberg of the king's plight. It provides a measure of how difficult it is to extend a material, with a value given by the ratio of tensile strength to tensile strain. This number is formally called the oxidation state. 0 0. The images may not be posted on any website, shared in any disc library, image storage mechanism, network system or similar arrangement.

Tantalum was discovered by the Swedish chemist Anders Ekeberg, who extracted the metal from mineral samples. Tantalum is relatively rare: it's the fiftieth commonest element in the earth's crust. The general formula is that the nth shell can in principle hold up to 2(n 2) electrons. 3D illustration of Tantalum as Element 73 of the Periodic Table. The presence of the f electrons is the difference: the f orbitals do a very poor job of shielding the valence electrons from the nucleus (because of the three angular nodes at the nucleus) so the effective nuclear charge of Ta is higher than that of Nb. In its pure state, tantalum is a grey-blue metal, which can be polished to a silvery sheen. A measure of how difficult it is to deform a material. Of course it depends on what one really means by the discovery of an element. Members of a group typically have similar properties and electron configurations in their outer shell.
