Vanadium

Element 23 of Periodic table is Vanadium with atomic number 23, atomic weight 50.9415. Vanadium, symbol V, has a Body Centered Cubic structure and Silver color. Vanadium is a Transition Metal element. It is part of group 5 (vanadium family). Know everything about Vanadium Facts, Physical Properties, Chemical Properties, Electronic configuration, Atomic and Crystal Structure.

History of Vanadium

The element Vanadium was discovered by M. del Río in year 1801 in Mexico and Sweden. Vanadium was first isolated by N.G.Sefström in 1830. Vanadium derived its name from Vanadis, an Old Norse name for the Scandinavian goddess Freyja.

Río found the metal in vanadinite but retracted the claim after Hippolyte Victor Collet-Descotilsdisputed it. Sefström isolated and named it, and later it was shown that Río had been right in the first place.

How to Locate Vanadium on Periodic Table

Periodic table is arranged by atomic number, number of protons in the nucleus which is same as number of electrons. The atomic number increases from left to right. Periodic table starts at top left ( Atomic number 1) and ends at bottom right (atomic number 118). Therefore you can directly look for atomic number 23 to find Vanadium on periodic table.

Another way to read periodic table and locate an element is by using group number (column) and period number (row). To locate Vanadium on periodic table look for cross section of group 5 and period 4 in the modern periodic table.

Crystal Structure of Vanadium

The solid state structure of Vanadium is Body Centered Cubic.

The Crystal structure can be described in terms of its unit Cell. The unit Cells repeats itself in three dimensional space to form the structure.

The unit cell is represented in terms of its lattice parameters, which are the lengths of the cell edges Lattice Constants (a[303 pm]b[303pm] and c[303pm]) and the angles between them Lattice Angles (alpha[π/2], beta[π/2] and gamma[π/2])

The positions of the atoms inside the unit cell are described by the set of atomic positions ( xi, yi, zi) measured from a reference lattice point.

The symmetry properties of the crystal are described by the concept of space groups. All possible symmetric arrangements of particles in three-dimensional space are described by the 230 space groups (219 distinct types, or 230 if chiral copies are considered distinct.

Ground State Electronic Configuration of Vanadium- neutral Vanadium atom

Abbreviated electronic configuration of Vanadium

The ground state abbreviated electronic configuration of Neutral Vanadium atom is [Ar] 3d3 4s2. The portion of Vanadium configuration that is equivalent to the noble gas of the preceding period, is abbreviated as [Ar]. For atoms with many electrons, this notation can become lengthy and so an abbreviated notation is used. This is important as it is the Valence electrons 3d3 4s2, electrons in the outermost shell that determine the chemical properties of the element.

Electrons are filled in atomic orbitals as per the order determined by the Aufbau principle, Pauli Exclusion Principle and Hund’s Rule.

  • As per the Aufbau principle the electrons will occupy the orbitals having lower energies before occupying higher energy orbitals. According to this principle, electrons are filled in the following order: 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, 7p…
  • The Pauli exclusion principle states that a maximum of two electrons, each having opposite spins, can fit in an orbital.
  • Hund’s rule states that every orbital in a given subshell is singly occupied by electrons before a second electron is filled in an orbital.

Use of Vanadium

Vanadium-steel alloys are used for armour plate, axles, tools, piston rods and crankshafts. Less than 1% of vanadium, and as little chromium, makes steel shock resistant and vibration resistant. Vanadium alloys are used in nuclear reactors because of vanadium’s low neutron-absorbing properties.
