What is Bohrium made of?
Bohrium is produced artificially and only small amounts have been made. The Dubna team created it by bombarding bismuth-204 (204Bi) with heavy nuclei of chromium-54 (54Cr). A rapidly rotating cylinder, coated with a thin layer of bismuth, was used as a target and bombarded with a stream of chromium fired tangentially.
What is Bohrium classified?
Bohrium is a chemical element with symbol Bh and atomic number 107. Classified as a transition metal, Bohrium is a solid at room temperature.
What is 107 on the periodic table?
This podcast is about one of these elements, number 107 in the periodic table, called bohrium. Transuranium elements are essentially made by slamming atoms of different elements into each other at very high speeds in the hope that such collisions will allow nuclei to fuse together to form atoms of a new element.
What is the period and group number of Bohrium?
It is a member of the 7th period and belongs to the group 7 elements as the fifth member of the 6d series of transition metals. Chemistry experiments have confirmed that bohrium behaves as the heavier homologue to rhenium in group 7.
How many valence electrons are in Bohrium?
107 electrons
Bohrium atoms have 107 electrons and the electronic shell structure is [2, 8, 18, 32, 32, 13, 2] with Atomic Term Symbol (Quantum Numbers) 6S5/2….Bohrium Atomic and Orbital Properties.

Bohrium/Atomic number
What are the properties of bohrium?
Bohrium is an artificially produced radioactive element. It is probably silvery or metallic gray. It’s most stable isotope, Bh-262 has an half life of 17 seconds. Bohrium does not have any known application and little is known about it.

What determines the atomic mass?
Atomic mass is the sum of the masses of the protons, neutrons, and electrons in an atom, or the average mass, in a group of atoms. However, electrons have so much less mass than protons and neutrons that they don’t factor into the calculation. So, the atomic mass is the sum of the masses of protons and neutrons.
What element has atomic mass?
The chemical element Hydrogen has an atomic mass of 1.008 amu. The chemical element Carbon has an atomic mass of 12 amu.
How is the element bohrium used?
Borium is used in farriery to improve traction for horses. Other applications include ploughshares, saw teeth, cane knives and drill bits. Borium should not be confused with the chemical elements barium, bohrium or boron , the last of which is called borium in a number of languages.
How to tell atomic mass?
1) Find the atomic weight. The atomic weight is typically printed below the element name on the periodic table, usually to two or three decimal places. 2) Round to the mass number. The mass number is the total number of protons and neutrons in one atom of an element. 3) Find the number of electrons. Atoms contain the same number of protons and electrons, so these numbers will be the same. 4) Calculate the number of neutrons. Now you know that atomic number = number of protons, and mass number = number of protons + number of neutrons. 5) Understand isotopes. An isotope is a specific form of an element, with a certain number of neutrons.
