Where is ytterbium commonly found?

Ytterbium and other rare earth elements are found in several rare minerals. It is most commonly recovered commercially from monazite sand (0.03% ytterbium). This element is also present in spodumene and xenotime.The main mining areas are China, USA, Brazil, India, Sri Lanka and Australia.

Who discovered ytterbium?

French chemist Jean-Charles-Galissard de Marignac An element called ytterbium was discovered. The erbium nitrate is heated with de Marignac until it is completely decomposed, and the residue is extracted, from which the two oxides are obtained. One oxide is called erbium oxide and the other is called ytterbium.

However, in recent years, some scientists Questioning the safety of lanthanidesIn healthcare, for example, some MRI patients attribute a range of side effects, including long-term kidney damage, to their exposure to the commonly used MRI contrast agent, the lanthanide gadolinium.

Why is the third shell 8 or 18?

Each shell can only contain a fixed number of electrons, up to two electrons can hold the first shell, up to eight (2+6) electrons can hold the second shell, and up to 18 (2 + 6 + 10) A third shell can be installed, etc. The general formula is that the nth shell can in principle hold up to 2(n2) electrons.
