Bohrium (Bh) is a synthetic chemical element, not a compound or molecule composed of multiple atoms. Therefore, when asking "how many atoms are in Bohrium," one is fundamentally referring to the defining characteristics and subatomic particles that constitute a single atom of this element. Each individual unit of Bohrium is, by definition, an atom.
Defining an Atom of Bohrium
An atom of Bohrium is uniquely identified by its atomic number. The provided reference indicates that Bohrium has an atomic number of 107. This number is crucial as it represents the exact count of protons found within the nucleus of every Bohrium atom.
- Protons: The atomic number of 107 means that every Bohrium atom contains 107 protons in its nucleus. Protons are positively charged subatomic particles that determine an element's identity.
- Electrons: In a neutral atom of Bohrium, the number of electrons orbiting the nucleus is equal to the number of protons. Therefore, a neutral Bohrium atom also possesses 107 electrons. Electrons are negatively charged particles that dictate an atom's chemical behavior.
- Neutrons: The number of neutrons in a Bohrium atom can vary, leading to different isotopes of the element. Neutrons are neutral subatomic particles found in the nucleus along with protons. While they don't change the element's identity, they do affect its atomic mass and stability.
The Atomic Structure of Bohrium
The structure of a Bohrium atom, like all atoms, consists of a dense central nucleus surrounded by a cloud of electrons.
- Nucleus: At the heart of a Bohrium atom lies its nucleus, containing 107 protons and a varying number of neutrons. For example, the most stable known isotope, Bohrium-270 (²⁷⁰Bh), has 107 protons and 163 neutrons (270 - 107 = 163).
- Electron Shells: The 107 electrons are arranged in specific energy levels or shells around the nucleus. While the exact electron configuration for such a superheavy element is complex and theoretical, it follows the general principles of quantum mechanics.
Key Characteristics of a Bohrium Atom
Bohrium is a fascinating element due to its synthetic nature and extreme instability. Understanding its atomic composition is key to appreciating its place on the periodic table.

Isotopes and Atomic Mass
Since the number of neutrons in a Bohrium atom can differ, Bohrium exists in various isotopic forms. Each isotope of Bohrium will still contain 107 protons, but the sum of its protons and neutrons (its mass number) will vary. For instance:
- Bohrium-270 (²⁷⁰Bh): An atom of this isotope contains 107 protons and 163 neutrons.
- Bohrium-267 (²⁶⁷Bh): An atom of this isotope contains 107 protons and 160 neutrons.
These isotopes are produced in laboratories through nuclear fusion reactions and have extremely short half-lives, often measured in seconds or milliseconds, making their study incredibly challenging.
