The first visible amounts of a pure berkelium compound, berkelium chloride, was produced in 1962. Interactive periodic table with up-to-date element property data collected from authoritative sources. The number of electrons in each of berkelium's shells is 2, 8, 18, 32, 27, 8, 2 and its electron configuration is [Rn] 5f 9 7s 2. Berkelium behaves as a paramagnetic material at room temperature and low temperatures. This article summarizes key chemical and thermal properties of this chemical element and atom. At very low temperature (-239 degree centigrade or less) it undergoes transition to an antiferromagnetic state. Atomic mass of Berkelium is 247 u. Here is a list of elements of the periodic table, their atomic numbers, and element symbols.The list is ordered by increasing atomic number, which is the number of protons in an atom of that element. Now write the isotopic notation for carbon-14. The chemical symbol for Berkelium is Bk.. Atomic Mass of Berkelium. Berkelium was first made some 60 years ago by Stan Thomson, Al Ghiroso and Glen Seaborg by bombarding the isotope americium-241 with alpha particles. The name carbon-14 tells us that this isotope's mass number is #14#. Atomic Number of Berkelium. For the Periodic Table, the Atomic Number is on top and the average atomic mass is on the bottom. Note: in hyphen notation, the number after the hyphen is the mass number (protons + neutrons). Chemical Characteristics. Look up chemical element names, symbols, atomic masses and other properties, visualize trends, or even test your elements knowledge by playing a periodic table game! Berkelium has an atomic number 97 and is represented by symbol Bk. Each element has a symbol, which is a one- or two-letter abbreviation of its name. Berkelium is a Block F, Group 3, Period 7 element. For other isotopes, the isotopic mass usually differs and is usually within 0.1 u of the mass number. Example 1: What is the isotopic notation for the isotope carbon-14? Berkelium Properties. In its elemental form, berkelium's CAS number is 7440-40-6. ... since the atomic mass unit is defined from it. Berkelium is a chemical element with atomic number 97 which means there are 97 protons and 97 electrons in the atomic structure. Berkelium - Periodic Table - Atomic Number - Mass - Radius - Density. The half-life of the first isotope of berkelium to be produced in this way was a healthy 4.5 hours. It weighed 1 billionth of a gram. #""_6^14"C"# What is Berkelium - Properties of Berkelium Element - Symbol Bk .

The metal is silver colored, quite soluble in dilute mineral acids, and readily oxidized in air or oxygen to form the oxide. The berkelium atom has a radius of Technical data for Berkelium Click any property name to see plots of that property for all the elements. Berkelium was first prepared in elemental form in 1968 and weighed 1.7 micrograms. 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. From the periodic table, we see that the atomic number (number of protons) for the element carbon is #6#. In comparison to other elements, Berkelium has different structure and radius and therefore it has different atomic mass and density. Berkelium is a radioactive element.
