Thorium Atomic Structure

Thorium atomic structure provides properties of its atom. Atomic structure of Thorium includes atomic number, atomic weight, electron configuration, atomic radius, etc. The atom or the nucleus of this metal consists of 90 protons, 142 neutrons and 90 electrons. Apart from the atomic structure of Thorium, you can find amazing information and interesting Facts About Thorium. The lattice constant and lattice Angles, refers to the physical dimension of its unit cells. 3D lattices generally have three lattice constants which are commonly referred as a, b, and c and their respective values are π/2, π/2, π/2 and its constat's value is 508.42 pm.

Thorium Atomic Number

The atomic number of Thorium is 90. Thorium atomic number signifies the total number of protons or electrons present inside its atom. Under normal conditions, the number of electrons and protons are equal, making the net charge of an atom return to zero. Atomic structure of Thorium depends upon the total number of electrons, neutrons and protons present in its nucleus. Atomic number largely determines the atomic size, electronegativity, valency and other such factors. Atomic weight is the weight of the atom as whole, the weight corresponding to all the atomic particles. The atomic weight of Thorium is 232.04 amu whereas its volume is 19.90 cm3/mol. Atomic radius of Thorium is 179.80 pm and its covalent radius is 206.00 pm.

Thorium Electron Configuration

Thorium electron configuration explains the electron distribution in different orbits of the atom. The electron configuration plays a significant role in determining the position of Thorium In Periodic Table. The electron configuration of Thorium is [Rn] 6d2 7s2. The value of valence electron potential of this element is 59.30 (-eV). It is calculated using (-eV)= kn/r equation.

Crystal Structure of Thorium

Crystal structure of Thorium plays an important role in determining the other Physical Properties of Thorium. Its crystal structure shows the unique arrangement of atoms inside a crystal which helps in deconding the atomic structure of Thorium metal. Thorium crystal structure is Face Centered Cubic (FCC). FCC is a basis type of cubic crystal structure. In crystallography, the cubic crystals structure is a crystal system where the unit cell has a cube shaped structure. This is one of the simplest crystal structure found in crystals of metal. All these atomic properties of Thorium are related to its atomic structure.
