The number of electrons in each element’s electron shells, particularly the outermost valence shell, is the primary factor in determining its chemical bonding behavior. Ytterbium is found in the ore monazite sand [(Ce, La, etc.) Earlier, in 1843, erbium and terbium were extracted from yttria and then ytterbium was separated from erbium. The carbon family is also known as the carbon group, group 14, or the tetrels. Ytterbium atomic radius is 222 pm, while it's covalent radius is N/A. Chemistry. All possible Values are given for typical oxidation number and coordination. Members of a group typically have similar properties and electron configurations in their outer shell. Periodic table starts at top left ( Atomic number 1) and In chemistry, valence electrons are the electrons that are located in the outermost electron shell of an element. A vertical column in the periodic table. derived its name from Ytterby, Sweden. Ytterbium is a lanthanide element. The only ytterbium compound of historical commercial use is ytterbium oxide (Yb2O3); this is used to make alloys and special types of glass and ceramics. It turns out that when the compound is heated, the electrons lost from the ytterbium atom form their own “cloud,” of sorts, outside of the atom.

Brian Clegg will be providing more insight into the reactions and naming of einsteinium in next week's Chemistry in its element. In fact, it is the 43rd most abundant element on earth and has a greater natural abundance than tin, bromine, uranium or arsenic. A higher recycling rate may reduce risk to supply. Ytterbium can also exist in the +2 valence state; its compounds are powerful reducing agents and it is capable of reducing water to hydrogen gas. The chemical symbol for Ytterbium is Yb. The availability of suitable substitutes for a given commodity. In its metallic form, ytterbium is a bright and shiny metal that is both ductile and malleable and is more reactive than the other lanthanide metals, quickly tarnishing in air as it reacts with oxygen. When the bomb exploded on November the first, 1952, it produced an explosion with the power of over 10 million tonnes of TNT - five hundred times the destructive power of the Nagasaki explosion. It is defined as being the charge that an atom would have if all bonds were ionic. In the case of Ytterbium the abbreviated electron configuration is [Xe] 4f14 6s2.

Element 70 of Periodic table is notation can become lengthy and so an abbreviated notation is used.This is important as it is This was achieved by heating erbium nitrate until it decomposed and then extracting the residue with water to obtain two oxides; a red one, which was identified as erbium oxide and a white powder, which was named ytterbium oxide. ytterbium yb Appearance: Silvery white Mass Number: 173 Atomic weight: 173.045 g/mol Electrons: 70 Protons: 70 Neutrons: 103 Atomic number (Z): 70 Period: 6 The mass of an atom relative to that of carbon-12. 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. 6 in the modern periodic table. Ytterbium, atomic number 70, is the first element in the Periodic table to have the first four shells full. However, more recently, some materials doped with ytterbium and erbium can be used to convert invisible infra red light into green and/or red light from the erbium ions; the ytterbium acts cooperatively with the erbium ions and effectively talks to or 'sentitises' the emission from the Er ion. in Periodic Table, Period Electronegativity (Pauling scale)The tendency of an atom to attract electrons towards itself, expressed on a relative scale. Let’s draw it out as a simple diagram. below for the Electrical properties of Ytterbium, Refer to table below for Thermal properties of Ytterbium. Isotopes of rhodium. It reacts slowly with cold water and it oxidizes slowly in air. The arrangements of electrons above the last (closed shell) noble gas. Ytterbium is beginning to find a variety of uses, such as in memory devices and tuneable lasers. It is given by the ratio of the shear stress to the shear strain. It has low toxicity. It melts at 824 degrees Celsius. Instead of placing the bank note under UV light to see the security encoding, an infra red laser pen is used to reveal the luminescence colours of erbium, clever hey? This is where the artist explains his interpretation of the element and the science behind the picture. ... State the number of valence electrons in an atom of Sulfur. 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 … A measure of how difficult it is to compress a substance. We welcome your feedback. This lanthanide metal is a bright, shiny surface, and is quite soft, malleable and ductile. Ytterbium is named after Ytterby, Sweden. Nevertheless, check the complete configuration and other interesting facts about Ytterbium that most people don't know. It can be found in gadolinite, monazite, and xenotime. Some elements exist in several different structural forms, called allotropes. In this regard, small amounts of Yb-169 have been exploited in portable X-ray machines that require no electricity and are much easier to carry around than conventional X-ray machines-useful for radiography of small objects! It is given by the ratio of the pressure on a body to the fractional decrease in volume.
