Each element has a symbol, which is a one- or two-letter abbreviation of its name. Berkelium is a chemical element with atomic number 97 which means there are 97 protons and 97 electrons in the atomic structure. The berkelium atom has a radius of 170.pm. Berkelium was first prepared in elemental form in 1968 and weighed 1.7 micrograms. The first visible amounts of a pure berkelium compound, berkelium chloride, was produced in 1962. The name carbon-14 tells us that this isotope's mass number is #14#. Berkelium - Periodic Table - Atomic Number - Mass - Radius - Density. What is Berkelium - Properties of Berkelium Element - Symbol Bk . 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. Berkelium is a Block F, Group 3, Period 7 element. Technical data for Berkelium Click any property name to see plots of that property for all the elements. In its elemental form, berkelium's CAS number is 7440-40-6. At very low temperature (-239 degree centigrade or less) it undergoes transition to an antiferromagnetic state.

In comparison to other elements, Berkelium has different structure and radius and therefore it has different atomic mass and density. Chemical Characteristics. Example 1: What is the isotopic notation for the isotope carbon-14? From the periodic table, we see that the atomic number (number of protons) for the element carbon is #6#. 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. This article summarizes key chemical and thermal properties of this chemical element and atom. Berkelium has an atomic number 97 and is represented by symbol Bk. It weighed 1 billionth of a gram. Atomic Number of Berkelium. Berkelium behaves as a paramagnetic material at room temperature and low temperatures. The metal is silver colored, quite soluble in dilute mineral acids, and readily oxidized in air or oxygen to form the oxide. The chemical symbol for carbon is #"C"#. Note: in hyphen notation, the number after the hyphen is the mass number (protons + neutrons). For the Periodic Table, the Atomic Number is on top and the average atomic mass is on the bottom. The half-life of the first isotope of berkelium to be produced in this way was a healthy 4.5 hours. 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. Berkelium is a radioactive element. For other isotopes, the isotopic mass usually differs and is usually within 0.1 u of the mass number. 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 Properties. #""_6^14"C"# Atomic mass of Berkelium is 247 u.
