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.
Vanadium History
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.
| Discovered By | M. del Río |
| Discovery Date | 1801 in Mexico and Sweden |
| First Isolation | 1830 |
| Isolated by | N.G.Sefström |
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.
Vanadium Uses
Vanadium is used in jet engines and aircraft components. All of its uses require it to be mixed with another metal or element, such as Vanadium-gallium tape used in magnets. About 80% of the vanadium created is used as a steel additive to produce a tough alloy.

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.

Spectral Lines of Vanadium - Atomic Spectrum of Vanadium
A spectral line is a dark or bright line in an otherwise uniform and continuous spectrum, resulting from an excess or deficiency of photons in a narrow frequency range, compared with the nearby frequencies. Spectral lines are often used to identify atoms and molecules.
Spectral lines are the result of interaction between a quantum system and a single photon. A spectral line may be observed either as an emission line or an absorption line.
Spectral lines are highly atom-specific, and can be used to identify the chemical composition of any medium. Several elements, including helium, thallium, and caesium, were discovered by spectroscopic means. They are widely used to determine the physical conditions of stars and other celestial bodies that cannot be analyzed by other means.
