Density is defined as the mass per unit volume. Usually, elements will have ferromagnetic and antiferromagnetic properties at low temperatures but it is paramagnetic at a temperature of 0.1 Kelvin. Ytterbium was discovered by Jean Charles Galissard de Marignac in 1878, in Geneva, Switzerland.He heated erbium nitrate until it decomposed and then extracted the residue, which contained an unknown white powder that he named ytterbium oxide (ytterbia). A measure of how difficult it is to compress a substance. Ar(Yb) = 173.045(10) since 2015 The total number of neutrons in the nucleus of an atom is called the neutron number of the atom and is given the symbol N. Actinium is a soft, silvery-white radioactive metal. It is used in metallurgical and chemical experiments. Ytterbium, which was first obtained in a pure state just some 50 years ago, only two calibrated measurements of its isotopic composition have been ever made. Yttrium's atomic number is 39, meaning that it always has 39 protons in its nucleus. Typical densities of various substances are at atmospheric pressure. The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 coulombs. Due to the quantum nature of electrons, the electrons are not point particles, they are smeared out over the whole atom. The naturally occurring ytterbium is a mixture of seven stable isotopes with mass numbers 168, 170 to 174 and 176. The nucleus is composed of protons and neutrons. (1), (2)In 1907, in Paris, George Urbain separated ytterbia into two constituents. It reacts slowly with cold water and it oxidizes slowly in air. Therefore, there are various non-equivalent definitions of atomic radius. One atomic mass unit is equal to 1.66 x 10-24 grams. Ytterbium has a bright silvery lustre, is soft, malleable, and quite ductile. The ordering of the electrons in the ground state of multielectron atoms, starts with the lowest energy state (ground state) and moves progressively from there up the energy scale until each of the atom’s electrons has been assigned a unique set of quantum numbers. 1) You may use almost everything for non-commercial and educational use. Density is defined as the mass per unit volume. It is a synthetic element (first synthesised at Hasse in Germany) and radioactive. Hassium is a chemical element with symbol Hs and atomic number 108. A measure of how difficult it is to deform a material. The Van der Waals radius, rw, of an atom is the radius of an imaginary hard sphere representing the distance of closest approach for another atom.

The density of a material varies with temperature and pressure. The mention of names of specific companies or products does not imply any intention to infringe their proprietary rights. If we include man made elements, the densest so far is Hassium. Since nucleons (protons and neutrons) make up most of the mass of ordinary atoms, the density of normal matter tends to be limited by how closely we can pack these nucleons and depends on the internal atomic structure of a substance. He performed a series of fractional crystallizations of ytterbium nitrate from nitric acid solution and ob… Main purpose of this project is to help the public to learn some interesting and important information about chemical elements and many common materials. This variation is typically small for solids and liquids but much greater for gases. Ytterbium (pronounced i-TER-bee-əm) is a chemical element with the symbol Yb and atomic number 70 (One but last member of the group Lanthanides).Not to be … In a neutral atom there are as many electrons as protons moving about nucleus. Atomic Mass of Yttrium Atomic mass of Yttrium is 88.90585 We assume no responsibility for consequences which may arise from the use of information from this website. In light of new mass-spectrometric determinations, the Commission recommended Ar (Yb) = 173.054 (5) in 2007. This fact has key implications for the building up of the periodic table of elements. For uranium atom, the Van der Waals radius is about 186 pm = 1.86 ×10−10m. Not to be confused with element ytterbium (Yb). As a result of this expansion, the density of most materials decreases. The atom consist of a small but massive nucleus surrounded by a cloud of rapidly moving electrons. This is approximately the sum of the number of protons and neutrons in the nucleus. agreement. Mass was no longer considered unchangeable in the closed system.    Crystal Structure, Element Groups: The atomic mass or relative isotopic mass refers to the mass of a single particle, and therefore is tied to a certain specific isotope of an element. Units of measure have been defined for mass and energy on the atomic scale to make measurements more convenient to express. Erbium – Periodic Table – Atomic Number – Mass – Radius – Density, Lutetium – Periodic Table – Atomic Number – Mass – Radius – Density.

Ytterbium compounds are capable of absorbing light in the near infra red part of the electromagnetic spectrum, which has been exploited to convert radiant energy into electrical energy in devices coupled to solar cells.

The volume of an atom is about 15 orders of magnitude larger than the volume of a nucleus. As a result, the electron cloud contracts and the atomic radius decreases. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z. See also: Atomic Mass Number – Does it conserve in a nuclear reaction? The densest material found on earth is the metal osmium, but its density pales by comparison to the densities of exotic astronomical objects such as white dwarf stars and neutron stars. This dependence is usually expressed by the coefficient of linear or volume expansion. On the periodic table of the elements, atomic radius tends to increase when moving down columns, but decrease when moving across rows (left to right). For example, 63Cu (29 protons and 34 neutrons) has a mass number of 63 and an isotopic mass in its nuclear ground state is 62.91367 u. For other isotopes, the isotopic mass usually differs and is usually within 0.1 u of the mass number. Element Ytterbium (Yb), Group 19, Atomic Number 70, f-block, Mass 173.045. It may seem, that the space and in fact the matter is empty, but it is not.    Electron Configuration On the atomic scale, physicists have found that quantum mechanics describes things very well on that scale. Mass numbers of typical isotopes of Ytterbium are 170-174, 176. Yttrium is a chemical element with atomic number 39 which means there are 39 protons and 39 electrons in the atomic structure. The nucleus is composed of protons and neutrons. Ytterbium is a soft, malleable and ductile chemical element that displays a bright silvery luster when pure. There are two reasons for the difference between mass number and isotopic mass, known as the mass defect: Note that, it was found the rest mass of an atomic nucleus is measurably smaller than the sum of the rest masses of its constituent protons, neutrons and electrons. It is the electrons that are responsible for the chemical bavavior of atoms, and which identify the various chemical elements. This page was created by Yinon Bentor.    Transition Metals The size and mass of atoms are so small that the use of normal measuring units, while possible, is often inconvenient. Increasing the pressure on an material (especially for liquids or gases) decreases the volume of the object and thus increases its density via the atomic number density. It is the Pauli exclusion principle that requires the electrons in an atom to occupy different energy levels instead of them all condensing in the ground state. Seven naturally occurring isotopes of ytterbium are known ranging from mass numbers 168 to 176.

Therefore the space in an atom (between electrons and an atomic nucleus) is not empty, but it is filled by a probability density function of electrons (usually known as  “electron cloud“). Because of its closed-shell electron configuration, its density and melting and boiling points differ significantly from those of most other lanthanides. Use of this web site is restricted by this site's license The atomic mass is carried by the atomic nucleus, which occupies only about 10-12 of the total volume of the atom or less, but it contains all the positive charge and at least 99.95% of the total mass of the atom. Since the density (ρ) of a substance is the total mass (m) of that substance divided by the total volume (V) occupied by that substance, it is obvious, the density of a substance strongly depends on its atomic mass and also on the atomic number density (N; atoms/cm3). About This Site Ytterbium Symbol Yb Atomic Number 70 Atomic Mass 173.04 atomic mass units Number of Protons 70 Number of Neutrons 103 Number of Electrons 70 Melting … But this “huge” space is occupied primarily by electrons, because the nucleus occupies only about 1721×10−45 m3 of space. The unit of measure for mass is the atomic mass unit (amu). The chemical symbol for Ytterbium is Yb. However, this assumes the atom to exhibit a spherical shape, which is only obeyed for atoms in vacuum or free space.    Atomic Mass It is an intensive property, which is mathematically defined as mass divided by volume: The atom consist of a small but massive nucleus surrounded by a cloud of rapidly moving electrons. Atomic mass of Ytterbium is 173.04 u. Here are interesting facts about element Yb, as well as a summary of key atomic data: The mass of an atom relative to that of carbon-12.
