The atom consist of a small but massive nucleus surrounded by a cloud of rapidly moving electrons. Ytterbium has 70 protons and electrons in its structure. When ytterbium is hydrogenated up to the dihydride (orthorhombic phase) the two hydrogen (deuterium) atoms per unit cell, add two extra electrons to the system and also two extra low-lying bands below the Fermi level due to the hybridization of the hydrogen 1s and ytterbium 5d6s states . Q. Here is a table of element valences. It is a silvery-metallic transition metal chemically similar to the lanthanides and has often been classified as a "rare-earth element". The most common isotope of ytterbium has 70 protons and 104 neutrons in the nucleus. Also, shells don't stack neatly one on top of another, so don't always assume an element's valence is determined by the number of electrons … Experimental evidence (1) indicates that the 4f electrons are part of the atomic core for all the rare-earth metals. binary mixed valence compounds, ytterbium borides, and propose that various correlated topological phases, in particular a new topological crystalline Kondo insulator [29–31], can be realized. Having two valence electrons, this element is fairly stable, but more reactive than other lanthanide elements. The concept of “valence” — the ability of a particular atom to combine with other atoms by exchanging electrons — is one of the cornerstones of modern chemistry and solid-state physics.
